Purpose. As a secondary analysis, we reassess the association of initial congenital cataract surgery times, compliance to amblyopia therapy, and visual outcomes for a long-term follow-up in a secondary IOL implantation. Methods. Retrospective review of records of all infants with congenital cataracts who underwent secondary IOL implantation in the Eye and ENT Hospital of Fudan University from January 1, 2001, to December 31, 2007, and the minimum follow-up period was 5 years. Multiple regression analysis was used and the possible confounding factors were also analyzed to assess the effect on visual outcome. Results. A total of 110 patients (male: 59.1%) were included. The median (min–max) age at cataract extraction and IOL implantation was 7.5 (3.0–15.0) and 35.0 (22.0–184.0) months, respectively, and the average follow-up period was 99.3 ± 23.6 months. The median (min–max) BCVA at final follow-up was 0.20 (0.01–1.00). Compliance to amblyopia therapy was none, poor, and good in 21.8%, 24.5%, and 53.6%, respectively. Postoperative BCVA [logMAR, median (min–max) 0.70 (0.00–2.00)] linearly decreased with increasing cataract extraction time (per month) (β=0.04, 95% CI: 0.03–0.06, p<0.0001) in multivariable models with laterality and compliance to amblyopia therapy adjusted. Good compliance to amblyopia therapy was associated with better BCVA (logMAR) at last follow-up (β=−0.40, 95% CI = −0.53 to −0.27, p<0.0001) with laterality, opacity type, and extraction time adjusted. Conclusions. For Chinese infants with congenital cataract, an earlier primary congenital cataract surgery at an age of 3 to 15 months is associated with a better visual outcome. Good compliance to amblyopia therapy was also significant to visual outcome.

Background/Aim. Cataract surgery has become one of the safest procedures in medicine thanks to advances in technology and surgical techniques. Although minimal, we still witness different complications. The aim of this study was to compare visual outcome and complication rate in different techniques of cataract surgery, ie in cataract surgeries with various corneal incision width. Methods. The study included 3,457 consecutive patients, ie 4,670 eyes that had undergone cataract surgery. The used surgical techniques were: extracapsular cataract extraction, phacoemulsification/ forceps IOL implantation, phacoemulsification/ injector IOL implantation, microincision cataract surgery (MICS). Patient follow up was 6 months. Patients were evaluated for: visual aquity, corneal astigmatism, cellular reaction in the anterior chamber, IOL position. Results. Uncorrected visual aquity 30 days postoperatively was ? 0.5 in 30% of the eyes - ECCE; 54.7% of the eyes - phacoemulsification/forceps IOL implantation; 63.0% of the eyes - phacoemulsification/injector IOL implantation; 5/8 of the eyes - MICS. Endophthalmitis was detected in 0.15% of the eyes - ECCE and 0.1% of the eyes - phacoemulsification/forceps IOL implantation. In eyes with phacoemulsification/injector IOL implantation or microincision cataract surgery (MICS) there were no cases of endophthalmitis. After a 6-month period intraocular lens were dislocated in 7.2% of the eyes - ECCE, and 0.6% of the eyes - phacoemulsification/PMMA IOL. There was no IOL dislocation in other surgical techniques. Conclusion. Shorter corneal incision implies less complications, less operative trauma, faster visual rehabilitation and better visual outcome.

Objectives: To compare visual outcomes, principally myopic shift, visual acuity, intraocular pressure and strabismus between primary and secondary intraocular lens (IOL) implantation following congenital cataract surgery. Methods: A retrospective study of the long-term ocular outcomes in primary versus secondary IOL implantation (IOL-I) following congenital cataract surgery was conducted. We analyzed the files of all children with congenital cataract who underwent unilateral or bilateral lensectomy, posterior capsulotomy and anterior vitrectomy followed by primary or secondary IOL-I between 2000 to 2012, at King Abdulaziz University Hospital, Jeddah. Preoperative and postoperative assessment of each operated eye in terms of axial length, refractive errors, strabismus as well as (post IOL-I) intraocular pressure (IOP) and best corrected visual acuity (BC-VA) were collected and analyzed. Results: Data of 26 eyes of 14 patients (9 males, 6 females) was analyzed: 16 (61.5%) eyes underwent lensectomty and anterior vasectomy with primary IOL-I and 10 (38.5%) eyes underwent lumpectomy and anterior vasectomy with secondary IOL-I. Mean age at cataract surgery was 67.53 (± 48.70) months in the group of primary IOL-I versus 5.90 (± 3.72) months in the group of secondary IOL-I; and patients were followed up for 49.33 (± 26.23) versus 86.50 (± 23.36) months, respectively (p=.051). In the secondary IOL-I group, the mean of time from primary lensectomy to IOL-I was 50.44 (± 18.41) months. Last BC-VA showed better outcomes in primary IOL-I group as 10 eyes (83.3%) with good VA versus only 2 eyes (20%) in the secondary IOL-I, (p=0.009). Myopic shift was greater in secondary IOL group 10.86 (± 11.62) versus 0.19 (± 2.38) diopters (D) in primary IOL (p=0.046*); while no significant difference was observed in IOP (p=0.697). No case of isotropic was detected in primary versus 6 cases in the secondary IOL group. Conclusion: Visual outcomes, including visual acuity, strabismus and myopic shift were better in the group of children who underwent primary IOL implantation at age of >2 years, when compared to those with secondary IOL implantation at the age of <2 years, following congenital cataract surgery. However, poor visual acuity in the secondary IOL group was mainly explained by the relatively higher prevalence of eye complications in this group.

Objective. The purpose of this study was to study the imaging features of ultrasound biomicroscopy (UBM) in the aphakia with visual axis opacification (VAO) after congenital cataract surgery. Methods. From May 2015 to May 2018, aphakia patients with VAO who underwent congenital cataract surgery were examined by high-resolution bag/balloon UBM technique, and the results of UBM imaging were analyzed. According to UBM imaging features, different types of VAO were classified. Results. A total of 38 children (55 eyes) with VAO were included. 17 patients were bilateral, and 21 patients were unilateral. Patients with VAO were classified into 3 groups according to the UBM imaging features: membranous fibrosis VOA (17 cases, 28 eyes), cortical regeneration VOA (15 cases, 20 eyes), and mixed VOA (6 cases, 7 eyes). The patients in the membranous fibrosis group underwent Nd:YAG laser posterior capsulotomy, those in the cortical regeneration group underwent anterior vitrectomy, and those in the mixed type group underwent anterior vitrectomy with RF capsulotomy tip. After surgery, VAO were removed in all patients. During the follow-up period, in the membranous fibrotic VAO group, iris adhesion and pupillary occlusion were found in 2 eyes, and anterior vitrectomy combined with separation of iris adhesion was performed. In cortical regenerative and mixed type VAO groups, anterior vitrectomy was performed without opacity in the axial region. The total recurrence rate of VAO was 3.46%. Conclusion. After congenital cataract surgery, the UBM imaging features of aphakia with VAO are helpful to evaluate the condition of VAO before reoperation so as to choose the optimal surgical method to achieve better therapeutic effect.

Abstract Background: The incidence of nucleus drop or intraocular lens (IOL) drop as the complication of phacoemulsification increases due to the increased frequency of phacoemulsification. Pars plana vitrectomy (PPV) followed by endofragmentation and secondary IOL implantation is the choice of procedure for management. This study aims to determine the frequency, outcomes, and complication of PPV in the case of nucleus drop or IOL drop in the Department of Ophthalmology, Fakultas Kedokteran Universitas Indonesia – Rumah Sakit Cipto Mangunkusumo (FKUI-RSCM) Methods: This study is a retrospective descriptive study conducted in the Vitreoretinal Division of the Department of Ophthalmology, FKUI - RSCM. Research data was taken from the medical records of all nucleus drop or IOL drop patients underwent PPV in January 2017-December 2017. Results: There were 19 cases studied. The incidence of nucleus drop occurred in phacoemulsification surgery techniques (94.7%) and ECCE techniques (5.3%). Vitrectomy surgery was performed ≤2 weeks in 31.6% and >2 weeks in 68.4% after the patient first arrived at the vitreoretinal clinic. Most pre-PPV visual acuity was 1/60-6/60 (47.1%). In the final follow-up, visual acuity improved from 6/45 to 6/6 occurred in 42.2% of cases. Complication after PPV and secondary IOL implantation include elevated IOP (10.5%), IOL decentration (5.3%), corneal decompensation (5.3%), macular edema (5.3%), and retinal detachment (5.3%). Conclusion: Nucleus drop or IOL drop generally occurs in phacoemulsification cataract surgery techniques. Improved visual acuity was achieved after PPV and secondary IOL implantation at the end of the follow-up period. Most common post-PPV complication is elevated IOP.

Purpose. The purpose of this study is to find prognostic factors associated with low visual acuity in patients experiencing vitreous loss during cataract surgery. Methods. A retrospective, noncomparative, interventional, case study of patients experiencing vitreous loss during cataract surgery. Data collected included demographics, best corrected visual acuity (BCVA), axial length (AL), presence of ocular comorbidity affecting central vision, timing of intraocular lens (IOL) implantation, position of the implanted lens, and the presence of corneal sutures. Low visual outcome was defined as BCVA < 20/40. Results. Overall, 179 patients (60.3% males) with a mean age of 73 ± 12 years and axial length of 23.5 ± 1.3 mm with a mean follow-up of 12 ± 13 months were included. In multivariable logistic regression analysis, low visual outcome was independently associated with persisting postoperative complications (OR 6.25, 95% CI 1.378–30.9), preexisting ocular comorbidities (OR 4.45, 95% CI 1.1–18.00), and secondary intraocular lens (IOL) implant (OR 10.36, 95% CI 1.8–60.00). Conversely, pars plana vitrectomy (PPV) for dislocated fragments of lens material, age > 70 years, gender, axial length, degree of surgeon, corneal suturing, and anterior chamber lens implantation were not found to have significant associations with low visual outcomes ( P > 0.05 ). Conclusions. Low visual outcome after vitreous loss during cataract surgery was associated with ocular comorbidities, secondary IOL implantation, development of cystoid macular edema, and additional surgical complications.

Trauma is an important cause of monocular blindness in the developing world. This study aims to determine the demo­graphic profile and visual outcome of cataract surgery among the children with traumatic cataract. It was a prospective and longitudinal study of 189 consecutive children below 16 years who underwent cataract surgery with intra ocular lens (IOL) implantation for traumatic cataract at Sagarmatha Choudhary Eye Hospital, Lahan, Nepal from October 2012 to March 2014. Assessment included visual acuity measurement in the Snellen’s chart or the Cardiff card, anterior segment examina­tion with slit lamp, dilated fundus examination with the help of +20D lens in indirect ophthalmoscope, B-scan ultrasonogra­phy of posterior segment and objective and subjective refraction. Follow up was scheduled at first post-operative day, at dis­charge, one month and three months. Cause and type of trauma, demographic factors, surgical intervention, complications, and visual acuity was recorded. Among 189, majority of them were males (73%) and the average age was 8.8±3.6 years. The time of presentation ranged from 3 days to 8 years (median age two months). Wooden stick was the most common cause of injury (34.4%). The average preoperative visual acuity in logMAR scale was 1.6. The average postoperative visual acuity in logMAR scale was 0.8. Eye injuries with traumatic cataract are associated with significant visual impairment. Cataract surgery with intraocular lens implantation restores vision significantly.

AIM: To determine the prevalence and visual outcomes after cataract surgery in different LIG patients METHODS:In this prospective study 50 patients were taken into study. Detailed history was taken and slit lamp examination was done & IOP was recorded by AT. All the patients were treated preoperatively appropriately. Patients were operated with SICS with PC IOL implantation and Peripheral Iridectomy.During follow up a detailed Ocular examination was done including Refraction using snellens chart and IOP measurement with AT. RESULTS: Among 50 patients 21(42%)were male patients and 29(58%)were female. Maximum patients had Phacomorphic Glaucoma accounting 72% (36patients) and Phacolytic Glaucoma 24%. Highest percentage was among 40-49mmHg (52%) followed by 30-39mmHg (36%) and >50mmHg (10%). Highest patients were between 10-19mmHg (76%). Visual acuity on admission, highest patients were seen in HM positive (64%) followed by PL+(32%). Even No PL were also seen (4%). On follow up after 6weeks ,majority were seen between 6/12- 6/18(52%) CONCLUSION: LIG is an important vision-threatening disease presenting as a painful red eye. It is remaining as one of the important cause of Blindness not only because of Senile cataract but even after cataract surgery due to Glaucoma caused by neglected cataractous lens.Hence, importance should be given for timely surgery for better visual outcome .

Purpose: To compare the visual outcome in patients of nucleus drop undergoing same day pars plana vitrectomy (PPV) versus delayed PPV. Methods: A prospective observational study was conducted on 50 eyes with posteriorly dislocated nucleus after cataract surgery who underwent PPV. Study variables included the time duration between nucleus drop and PPV, nal best-corrected visual acuity(BCVA), and complications after PPV. In 7(14%) eyes, PPV was performed on the same day of cataract surgery and in 43(86%) eyes, an elective PPV was performed after 1 week of cataract surgery. All our cases had intraocular lens(IOL) implanted at the end of PPV. Patients were followed up for 6 months with BCVA, intraocular pressure (IOP) measurement, indirect ophthalmoscopy and ocular coherence tomography(OCT).Results: Comparison was made between VA in patients who underwent PPV on same day (n=7) and those who underwent delayed PPV (n=43). In the same day group, 85.71% patients had BCVA ranged between 6/6 to 6/18, while only 14.29% had BCVA between 6/18 to 6/60 at the nal follow up. In the delayed PPV group , 60.47% had BCVA range between 6/6 to 6/18, 27.90% had BCVA ranged between 6/18 to 6/60 and only 11.63% patients had BCVA of <6/60- hand movements (HM) . Pvalue was 0.398 which was not statistically signicant.Conclusion: Majority of the patients obtain good VAafter PPVfor nucleus drop irrespective of the time. The visual outcome in both the groups was comparable, but slightly better results were obtained in the same day PPVgroup.
