Purpose. Few studies have focused on long-term postoperative visual quality. This study aimed to evaluate the long-term visual quality after microincision cataract surgery (MICS). Methods. 96 patients (144 eyes) diagnosed with age-related cataracts were enrolled in this one-year study. The patients underwent MICS and received aspheric monofocal intraocular lens implants. Uncorrected distance visual acuity (UDVA) was evaluated together with best-corrected distance visual acuity (BCDVA), best-corrected near visual acuity (BCNVA), contrast sensitivity, and surgically induced astigmatism (SIA). Results. Compared to preoperative measurements, UDVA, BCDVA, and BCNVA were significantly better after surgery (P<0.001), and they remained stable throughout follow-up. Contrast sensitivity was also significantly better after surgery (P<0.001). Mean SIA during follow-up was 0.57 ± 0.33 D at 1 week, 0.36 ± 0.25 D at 3 months, and 0.18 ± 0.16 D at 1 year. SIA decreased significantly during the postoperative period (P<0.001). The 1-year postoperative absolute residual diopter value was 0.32 ± 0.28 D. Conclusion. MICS can provide excellent visual quality as soon as on postoperative day 1, which persists during the follow-up period of 1 year. In contrast to previous studies, SIA decreases over time and may not completely stabilize for as long as 1 year postoperatively.

AIM: To assess the patient-reported outcome of phacoemulsification with posterior chamber single focus foldable intraocular lens (SIOL) using the Chinese version of Catquest-8SF questionnaire (Catquest-8SF-CN), evaluate the applicability of Catquest-8SF scale in northern Chinese and its sensitivity to cataract surgery. METHODS: Prospective clinical case follow-up study. The patients were recruited from the Central Hospital of Tai’an and completed the Catquest-8SF questionnaire by face-to-face interviews before and 3mo after surgery at the hospital. RESULTS: A total of 120 cataract patients with median age 67.6y and 52.5% female completed the Catquest-8SF. The Cronbach’s α coefficient of the total scale, daily-activity sub-table and comprehensive-evaluation sub-table were 0.861, 0.853 and 0.748 respectively. There was a high level of consistency between two investigators. The cumulative contribution rate was 66.64% by using the principal component analysis and the maximum variance orthogonal rotation method. The preoperative score of the Catquest-8SF-CN had a significant negative correlation with preoperative binocular mean weighted visual acuity and age (P<0.05), while a significant positive correlation with education level (F=6.094, P<0.001). The patients without systemic comorbidities got higher score than those who with (P<0.05). Three months after surgery, 102 (85%) patients came for follow-up and completed the questionnaire. Significant improvement of visual acuity was observed in both binocular and monocular surgery groups (t=10.404, P<0.001). There was higher improvement in binocular weighted visual acuity of binocular surgery group than in monocular surgery group (t=-20.77, P<0.001). The postoperative score was significantly higher in both groups than before (P<0.001). There was a significant improvement in the total score after cataract surgery. The 94 patients (92.2%) were very satisfied or satisfied with the operation; 92 patients (90.2%) thought the surgery achieved their expectations, and they all felt satisfactory. The degree of satisfaction was significantly correlated with the improvement score of the scale and it was also correlated with their expectation of the surgery. CONCLUSION: The Chinese version of Catquest-8SF questionnaire is suitable for the age-related cataract population in northern China. It is highly responsive to cataract surgery and brief, so it may have the potential to become part of a routine clinical assessment for cataract surgery in China. The patient’s overall satisfaction is high, which illustrates that the medical service we provide matches the patient’s needs. The degree of satisfaction was significantly correlated with the improvement score of the scale and it was also correlated with their expectation of the surgery.

Abstract Purpose To assess the changes in retinal vasculature and thickness after femtosecond laser-assisted cataract surgery (FLACS) using optical coherence tomography angiography (OCTA).Methods Fifty-six eyes of 56 patients with age-related cataract were enrolled in this study. Patients were divided into FLACS or conventional phacoemulsification surgery (CPS) due to the choice of operation. Vessel density (VD) and thickness at the macular area and optic nerve head (ONH) were checked by OCTA at baseline and at 1 day, 1 month and 3 months after cataract surgery.Results In the FLACS group: The radial peripapillary capillary (RPC) density displayed a significant reduction during the follow-up (P < 0.05), even when the retinal nerve fiber layer (RNFL) thickness was not significantly changed. There was a significant negative correlation between the changes in RPC density and femtosecond laser-assisted pre-treatment time (FLAPT) at 1 day and 1 month after cataract surgery respectively (both P < 0.05). At 3 months postoperatively, the macular thickness had a significant increase in all regions (all P < 0.05). In the CPS group, the retinal VD and thickness did not show statistically significant changes in all regions during the follow-up (all P > 0.05). However, the best corrected visual acuity (BCVA) was significantly improved in both groups postoperatively (both P < 0.001).Conclusions OCTA provided a promising analysis of retinal vascular alterations, demonstrating the reduction of RPC density and the increase of macular thickness after FLACS. However, these changes had no effect on the improvement of visual acuity after cataract surgery.

Aim. Functional and morphological macular study after cataract surgery in a group of diabetics without diabetic retinopathy compared to nondiabetics to evaluate the effect of surgical oxidative stress on diabetic retina.Methods. Prospective, comparative study. Preoperative eye exam, best corrected visual acuity (BCVA) measured by ETDRS letters, and optical coherence tomography (OCT) were followed by standard cataract surgery. The follow-up visits at 1, 3, and 6 months postoperatively included BCVA, OCT, and microperimetry, to analyze changes within and between the groups.Results. The BCVA improved significantly in diabetics and controls: 64.2 to 81.0 and 61.9 to 82.1 ETDRS at 6 months, respectively. The central macula at OCT significantly thickened in both groups, while the central 5 fields, corresponding to the microperimetry area, subclinically thickened from 284.20 to 291.18 μm at 6 months only in diabetics (p=0.026). A matching slight decrease in the microperimetry sensitivity from 1 to 6 months was found also only in diabetics, with mean average difference −0.75 dB (p=0.04).Conclusion. Underlying diabetes does not influence the surgical outcome in diabetics without diabetic retinopathy. However, slight thickening of wider macula and corresponding decrease in retinal sensitivity observed in diabetics 6 months postoperatively might influence visual function on long term.

Purpose To evaluate the efficacy and safety of the multifocal excimer laser corneal ablation profile (the Supracor procedure) in hyperopic presbyopia 1 year after laser treatment. Methods This prospective, consecutive, one-center, cross-sectional study included 20 patients with hyperopic presbyopia 1 year after treatment with the Supracor procedure. The main outcome measures were monocular uncorrected distance visual acuity (UDVA) and uncorrected near visual acuity (UNVA), photopic contrast sensitivity (Pelli-Robson charts), patient satisfaction, and functioning at 12 months. Results Thirty-nine eyes of 20 patients (mean age 59 ± 7.2 years) were treated. Mean UDVA improved from 0.56 ± 0.31 (mean 0.34 logMAR) preoperatively to 0.9 ± 0.15 (mean 0.06 logMAR) 12 months after surgery. Mean UNVA increased from 0.15 ± 0.07 (mean 0.84 logMAR) before surgery to 0.62 ± 0.24 (mean 0.23 logMAR) 12 months after treatment. Four eyes lost 2 lines of corrected distance visual acuity (10.3%). Monocular photopic contrast sensitivity was within age-correlated normal range (Pelli-Robson chart, mean contrast sensitivity 1.83 ± 0.18). A total of 75% of the patients would undergo Supracor again (1 not, 4 perhaps). The most frequently reported side effects were increased glare, reduced distance vision, and fluctuations in vision. Most patients used artificial tears. Conclusions One year after Supracor, UDVA and UNVA improved markedly, photopic contrast sensitivity was in normal age-correlated range, and the majority of patients (75%) was satisfied with the results. Side effects like loss of distance vision, fluctuations of vision, and increased glare have a greater influence on patient satisfaction than the improvement of spectacle-free near vision.

Background: Laser corneal refractive surgery suits, technology and nomograms are improving with time. This may improve the refractive and visual outcomes of the patients. Objectives: To evaluate the safety, efficacy, stability, and predictability of wavefront-optimized photorefractive keratectomy and Laser-assisted in-situ keratomileusis in patients with myopia and myopic astigmatism over 1-year using WaveLight® EX500 Excimer Laser machine. Methods: In this prospective cohort study, refractive and visual outcomes in 596 eyes (365 patients), either having myopia or myopic astigmatism were assessed. Patients were divided into Two groups: 1) Patients who underwent PRK (53 eyes have myopia and 217 eyes have myopic astigmatism), 2) Patients who underwent LASIK (53 eyes have myopia and 273 eyes have myopic astigmatism). Results: At 12 months postoperatively 94.3% of the myopic patients reached their preoperative best corrected distance visual acuity at the final one year follow up visit post PRK and LASIK. In patients with myopic astigmatism who underwent LASIK and PRK, 95.2%, and 96.3% of the patients reached their preoperative best corrected distance visual acuity at the final one year follow up visit post LASIK and PRK, respectively. The efficacy and safety indices were 1.00 or more for all groups with no eye lost any line of best corrected distance visual acuity. Conclusion: Our study results confirm the excellent efficacy, safety, good predictability and stability of myopia / myopic astigmatism correction by either wavefront- optimized LASIK or PRK over 1-year follow-up without significant differences between them using the WaveLight® EX500 excimer laser system.

Purpose. To evaluate the long-term efficacy, accuracy, stability, and safety of hyperopic laser in situ keratomileusis (LASIK) using a 213 nm wavelength solid-state laser. Methods. This prospective noncomparative case series consisted of 34 eyes of 17 patients which underwent hyperopic LASIK using a 213 nm solid-state laser (Pulzar Z1, CustomVis) at an outpatient refractive surgery center in Manila, Philippines. The preoperative and postoperative examinations included uncorrected distance visual acuity (UDVA), subjective manifest refraction, corrected distance visual acuity (CDVA), cycloplegic refraction, slitlamp biomicroscopy, and keratometry (). Main Outcome Measures. Accuracy, efficacy, stability, and safety of the refractive procedure. Results. Mean follow-up was months. At the end of follow-up, 26.47% had a UDVA of 20/20 and 94.12% had a UDVA of ≥20/40. Manifest refractive spherical equivalent (MRSE) was within ±0.50 D of the target refraction in 55.88% and within ±1.0 D in 85.30% of the study eyes. Refractive stability was noted in the 1st postoperative month while hyperopic regression was noted after the 3rd postoperative year. No eye lost more than 2 lines of CDVA. Conclusion. Our results show that the 213 nm solid state laser system is safe, effective, accurate, and predictable for the treatment of hyperopia.

Purpose To assess photopic and mesopic vision in patients implanted with 2 different trifocal intraocular lenses (IOLs). Methods Fifty patients with cataract in both eyes had surgery with bilateral implantation of a trifocal FineVision (FV, n = 25) or AT LISA tri 839MP (LisaTri, n = 25) IOL. Three months after surgery, high-contrast photopic uncorrected distance visual acuity and corrected distance visual acuity (CDVA) were determined using the Early Treatment Diabetic Retinopathy Study test. Intermediate (65 cm) and near (40 cm) visual acuity were also measured, both with best distance correction (DCIVA and DCNVA, respectively). The CSV1000 test chart was used for binocular and monocular contrast sensitivity. Defocus curves were constructed under photopic and mesopic conditions. Results Mean patient age was 68.4 ± 5.5 years (FV) and 67.3 ± 5.6 years (LisaTri) (p = 0.540). No differences were found in terms of visual acuity between the groups. The CDVA, DCIVA, and DCNVA were 0.05 ± 0.06, 0.25 ± 0.10, and 0.13 ± 0.10 logMAR for FV and -0.04 ± 0.11, 0.32 ± 0.09, and 0.12 ± 0.11 logMAR for LisaTri, respectively (p = 0.09, p = 0.08, and p = 0.12). Photopic and mesopic defocus curves were comparable between the 2 IOL groups (p>0.05). Mesopic values were significantly worse than photopic in both groups for all the measured values (p<0.001). No differences in contrast sensitivity were observed between the 2 IOL groups (p>0.05). Conclusions Both trifocal diffractive IOLs provided good visual quality with a statistically significant decrease in mesopic conditions.

Purpose. To assess anterior corneal surface stability 12 months following hyperopic LASIK correction with a light propagation algorithm.Setting. Vissum Instituto Oftalmológico de Alicante, Universidad Miguel Hernández, Alicante, Spain.Methods. This retrospective consecutive observational study includes 37 eyes of 37 patients treated with 6th-generation excimer laser platform (Schwind Amaris). Hyperopic LASIK was performed in all of them by the same surgeon (JLA) and completed 12-month follow-up. Corneal topography was analyzed with a light propagation algorithm, to assess the stability of the corneal outcomes along one year of follow-up.Results. Between three and twelve months postoperatively, an objective corneal power (OCP) regression of 0.39 D and 0.41 D was found for 6 mm and 9 mm central corneal zone, respectively. Subjective outcomes at the end of the follow-up period were as follows: 65% of eyes had spherical equivalent within ±0.50 D. 70% of eyes had an uncorrected distance visual acuity 20/20 or better. 86% of eyes had the same or better corrected distance visual acuity. In terms of stability, 0.14 D of regression was found. No statistically significant differences were found for all the study parameters evaluated at different postoperative moments over the 12-month period.Conclusions. Light propagation analysis confirms corneal surface stability following modern hyperopic LASIK with a 6th-generation excimer laser technology over a 12-month period.

Purpose. To investigate retinal function using microperimetry in patients affected by idiopathic epiretinal membrane (iERM) and cataract who underwent combined surgery: 4-year follow-up.Design. Prospective, interventional case series.Methods. 30 eyes of 30 consecutive patients with iERM and age-related cataract underwent 25-gauge vitrectomy and cataract surgery. At baseline, 90 and 180 days, and 1 and 4 years, we examined retinal mean sensitivity (MS), retinal mean defect (MD), fixation stability, and frequency of microscotomas using MP1 microperimetry. Best-corrected visual acuity (BCVA) and central retinal thickness (CRT) using a spectral domain optical coherence tomography (SD-OCT) were also performed.Results. All patients completed 1-year follow-up, while 23 patients reached last follow-up. Baseline MS and MD (10.48 ± 4.17 and −9.18 ± 4.40 dB) significantly changed at one year (12.33 ± 3.66 and −7.49 ± 3.31 dB,p<0.01), at four years (14.18 ± 3.46 and −4.66 ± 2.85,p<0.01), and between one and four years (p<0.01) after surgery. Compared to baseline, CRT and BCVA significantly changed at one year and remained stable at four years. No variations were observed in fixation stability and frequency of microscotomas compared to baseline.Conclusions. Long-term follow-up using microperimetry seems useful to evaluate patients after iERM surgery: retinal sensitivity changes even when BCVA and CRT remain stable.

The current treatment of neovascular age-related macular degeneration (nAMD) generates an excessive care pressure in the public health system. The search for a satisfactory treatment regimen, whose anatomical and functional stability may be achieved, is a challenge and a goal to be reached. We analyzed the outcomes in a patient cohort under fixed regimen treatment with intravitreal aflibercept (IVA). A retrospective study, with at least 1-year follow-up, in consecutive treated unselected naïve patients was carried out. Standard protocol was performed and evaluated at baseline, month 4 (after loading dose, LD), and month 12 (after fixed bimonthly regimen). One hundred six patients (123 eyes) aged 80.3 ± 7.7 years were included, receiving 6.8 ± 0.7 IVA. Visual acuity gain after LD was 5.5 ± 12.0 letters ( p < 0.0001 ). At month 12, 23 eyes (18.7%) gained ≥15 letters and 58 (47.1%) had best-corrected visual acuity ≥20/40 (70 letters). The improvement in visual acuity was lower in patients with polypoidal choroidal vasculopathy (+4.9 ± 18.1 letters; p = 0.2544) and somewhat higher in patients with retinal angiomatous proliferation (+5.4 ± 12.3 letters; p = 0.0373 ). Dry macula was present in only 9.8% of cohort at baseline vs. 69.7% at month 12 ( p < 0.0001 ). Atrophy was the most observed complication and related to the elderly patients. The average of follow-up visits was 3 ± 0.5. Functional and anatomical improvement were observed with IVA in a fixed bimonthly regimen treatment after LD, with results maintained up to one year with a good compliance. The fixed bimonthly regimen optimized patient management and logistic issues.
