Purpose To evaluate visual performance with trifocal and extended depth of focus IOL at 1 year post-operatively. Setting BMI Southend Hospital. Design Cohort study. Methods An age-matched cohort of forty subjects bilaterally implanted with the AT LISA 839MP trifocal IOL (20 patients, 40 eyes) and the Tecnis Symfony extended depth of focus IOL (20 patients, 40 eyes) were assessed at 3–6 months and 12–18 months post-operatively. Primary outcome measures were distance (6 m), intermediate (70 cm), near visual acuity (40 cm), and analysis of defocus profiles. Secondary outcomes included contrast sensitivity, Radner reading performance, quality of vision and assessment of halos. Results Distance visual acuity (VA) and defocus areas were similar ( p = 0.07). No significant difference in intermediate VA was noted but the intermediate area of focus was greater in the EDoF (0.31 ± 0.12 LogMAR*m−1) compared to the trifocal (0.22 ± 0.08LogMAR*m−1) ( p = 0.02). However, all near metrics were significantly better in the trifocal group. 80% of trifocal subjects were spectacle independent compared to 50% EDoF subjects. Quality of vision questionnaire found no significant differences between groups, however halo scores were greater at 3–6 months in the trifocal group ( p < 0.01) but no differences were noted at 12–18 months. Conclusions Near vision is significantly better for the trifocal, thus greater levels of spectacle independence. The range of intermediate vision was greater for the EDoF but no difference in intermediate VA. In the early period, differences in contrast sensitivity and halo size/intensity were noted, however, by one-year these measures were not significantly different.

Purpose To evaluate overall patient satisfaction, spectacle independence, visual acuity, and prevalence of optical phenomena following bilateral implantation of a new non-diffractive extended depth-of-focus intraocular lens targeted for minimonovision. Methods Multicenter prospective case series. Postoperative far and near visual acuity at 3 months and patient quality of life by NEI-VFQ-25 questionnaire were assessed. Postoperative evaluation included defocus curves analysis, spectacle independence assessment, and recording of photic phenomena. Results The study enrolled 97 eyes of 59 patients that underwent femtosecond-assisted cataract surgery with AcrySof IQ Vivity intraocular lens implantation. Thirty subjects (60 eyes) were eligible for analysis. After 3 months, postoperative achieved binocular uncorrected visual acuity was −0.03  ±  0.06 logarithm of the minimum angle of resolution for distance, 0.06  ±  0.06 logarithm of the minimum angle of resolution for intermediate, and 0.19  ±  0.03 logarithm of the minimum angle of resolution for near. Defocus curve showed a smooth profile with no abrupt decrease of visual acuity. Minimonovision significantly improved visual acuity compared to when minimonovision was neutralized, for values of defocus curves from −1 to −3 D ( p < 0.05). Twenty-six (87%) patients reported complete spectacle independence. High levels of satisfaction for distance and near vision resulted at VFQ-25 questionnaire. Only two patients complained of halos (6.7%) and one of them also of glare (3.3%). Conclusions Implantation of this new non-diffractive extended depth-of-focus intraocular lens with minimonovision resulted in satisfying far, intermediate, and near visual acuity with a consistent reduction of spectacle dependence and improvement in patient's quality of life.

Abstract Background This study aimed to assess visual outcomes, quality of vision and patients’ satisfaction of a trifocal diffractive intraocular lens after cataract surgery with phacoemulsification. Results The study included 36 eyes that underwent implantation of trifocal diffractive intraocular lens (IOL). The residual mean postoperative spherical equivalent was − 0.40 ± 0.29 diopters. Mean Uncorrected distance visual acuity was 0.80 ± 0.16 decimal (snellen equivalent 25 ft) while mean Uncorrected intermediate visual acuity was 0.82 ± 0.31 decimal (snellen equivalent 25 ft) and mean Uncorrected near visual acuity (UCNVA) was 0.87 ± 0.20 decimal (snellen equivalent 23 ft). In defocus curve, there was infinitesimal gradual change between the three foci. Contrast sensitivity was just below the inferior limit of normal. Conclusion Trifocal diffractive IOL created a true intermediate focus proved by VA and defocus curve and better quality of vision assessed by contrast sensitivity and high order aberration. Moreover, it was safe and effective for correcting distance and near vision in these patients. Most of the patients were very satisfied and achieved spectacle independence.

Abstract BackgroundDiabetic retinopathy (DR) and cataract are major complications that lead to significant visual impairment of diabetic patients. This study aims to compare the changes in visual acuity, quality of life and satisfaction after phacoemulsification between type 2 diabetic and nondiabetic patients.MethodsFifty-seven diabetic patients (37 with no diabetic retinopathy [DR], 11 with mild/moderate nonproliferative DR and 9 with severe nonproliferative/proliferative DR) and 45 controls were submitted to first-eye cataract surgery by phacoemulsification alone or with co-adjuvant intravitreal injection of bevacizumab or triamcinolone. National Eye Institute Visual Function Questionnaire (NEI VFQ-25) was recorded preoperatively and 6 months after surgery; and satisfaction evaluated at 1-month. ResultsCorrected distance visual acuity (CDVA) of the operated eye at 1 and 6-months (p<0.001) was significantly higher than preoperative value in the controls and all diabetic subgroups. The final CDVA in the severe nonproliferative/proliferative DR subgroup was significantly lower compared to the controls and the remaining diabetic subgroups (p<0.05). The mean NEI VFQ-25 composite score significantly improved in both control (15.413.2 points) and diabetic (15.413.0 points) groups, without differences among the diabetic subgroups (p>0.05). Overall patient satisfaction was 93% in both control and diabetic groups. ConclusionThis study provides vision-related patient-reported outcomes that support the benefit from phacoemulsification in all stages of DR, as long as there is adequate monitoring and treatment of retinopathy.

Purpose: The purpose of this study was to assess the clinical outcome after a bilateral implantation of an extended depth of focus intraocular lens in comparison to a monofocal intraocular lens. Setting: Department of Ophthalmology, Charité—Medical University Berlin, Germany. Patients and Methods: A total of 60 eyes of 30 patients were enrolled in this prospective, single-center study. The cataract patients underwent phacoemulsification with bilateral implantation of a TECNIS® Symfony (Abbott Medical Optics, Santa Ana, CA, USA, 15 patients) or a TECNIS Monofocal ZCB00 (Abbott Medical Optics, Santa Ana, CA, USA, 15 patients). Postoperative evaluations were performed after 1 and 3 months, including visual acuities at far, intermediate, and near distance. Mesopic, scotopic vision, and contrast sensitivity were investigated. Aberrometry was performed using an iTrace aberrometer with a pupil scan size of 5.0 mm. Results: After 3 months, the TECNIS Symfony group reached an uncorrected visual acuity at far distance of −0.02 logMAR compared to −0.06 logMAR in the TECNIS Monofocal group ( p = 0.03). Regarding the uncorrected vision at intermediate and near distance the following values were obtained: intermediate visual acuity −0.13 versus 0.0 logMAR (TECNIS Symfony vs TECNIS Monofocal, p = 0.001) and near visual acuity 0.11 versus 0.26 logMAR (TECNIS Symfony vs TECNIS Monofocal, p = 0.001). Low-contrast visual acuities were 0.27 versus 0.20 logMar (TECNIS Symfony vs TECNIS Monofocal, p = 0.023). Conclusion: The TECNIS Symfony intraocular lens can be considered an appropriate alternative to multifocal intraocular lenses because of good visual results at far, intermediate, and near distance as well as in low-contrast vision.

Abstract Purpose To assess the 1-month and 12-month postoperative visual performance and subjective outcomes following combined implantation of an extended depth of focus (EDOF) intraocular lens (IOL) and a trifocal IOL. Methods The study enrolled consecutive patients undergoing refractive lens extraction or cataract surgery with combined implantation of an EDOF IOL (dominant eye) and trifocal IOL. Uncorrected (UDVA) and best-corrected (CDVA) distance visual acuities, uncorrected intermediate (UIVA) and near (UNVA) visual acuities, and subjective questionnaires were evaluated 1 month and 12 months postoperatively. Results The study enrolled 58 consecutive patients. Binocular UDVA, UIVA and UNVA were − 0.08 ± 0.07 logMAR, 0.15 ± 0.14 logMAR and 0.17 ± 0.11 logMAR at 1 month, compared to − 0.09 ± 0.06 logMAR (P = .323), 0.11 ± 0.10 logMAR (P = .030) and 0.13 ± 0.10 logMAR (P = 0.008) at 12 months. Satisfaction was high with 93.1% of patients fulfilled or more than fulfilled postoperatively, and 84.5% and 86.3% reported spectacle independence for near at the respective postoperative assessments. The mean daytime and nighttime quality of vision (QoV) scores were 9.12 ± 0.94 and 7.88 ± 1.74 at 1 month, compared to 9.24 ± 0.78 (P = .183) and 8.26 ± 1.38 (P = .043) at 12 months. Conclusions This IOL combination provides good unaided visual acuity at 1 and 12 months postoperatively, with high functional vision and postoperative satisfaction reported at 1 and 12 months. However, a significant improvement in overall nighttime QoV at the 12 months assessment was found.

Purpose: To compare the post-op visual quality of spheric and aspheric acrylic yellow tinted intraocular lens following phacoemulsification cataract surgery. Place of study: Al-Majeed Laser Eye Hospital. Methods: Total 60 subjects (aged 40-65years) with age related mature cataracts were included. Data was assembled by non-probability convenient sampling technique at Al-Majeed Laser Eye Hospital. All patients presenting with mature cataract were include in this study without any other pathology and fundus abnormality. Pre and post-operative visual acuity was measured by using standard snellen visual acuity testing chart. For the purpose of accuracy repetitive values were taken for each patient. Post-operative vision was recorded one month followed by phacoemulsification. Comparisons was made between spheric and asphereic acrylic yellow tinted intraocular lens by applying (descriptive) statistics and paired sample t test for the analysis of results. Results: Quality of vision was compared post-operatively after implantation of aspheric hydrophilic acrylic IOL and spheric IOL in posterior chamber under the same phaco surgeon. All subjects after intra ocular implantation had better corrected visual acuity of 6/9 and more improved 6/6. There were found statistically differences in recorded visual acuity with aspheric yellow tinted iol implanation and spheric iol (p = 0.15) between the two types of intra-ocular lens. The mean, standard deviation, t-value found with spheric IOL were.1867, .18889, 2.517 respectively. However, of aspheric hydrophilic acrylic intra-ocular lens mean, standard deviation and t values found .800, .13493 and 2.5493 respectively. There was significant variance in statistics and quality of vision between the two types of lenses. Conclusions: This study concludes that post –operative improvement in quality of vision was better with aspheric hydrophilic yellow tinted lenses than spheric iol implantation. Implanting a foldable aspheric acrylic IOL gave much advantage in visual outcome to pseudophakes by protecting retina from light of shorter wavelength and decrease of chromatic aberration under the photopic circumstances particularly in subjects at hazard of age-related macular degeneration (AMD).
