Secondary Intraocular Lens Implantation

Aim. To conduct a retrospective analysis of secondary IOL implantation in patients who underwent PK with no simultaneous IOL implantation. Materials and Methods. The retrospective study of the secondary implantation of IOLs was conducted in 46 eyes that underwent a primary operation with PK and cataract/lens extraction with no IOL implantation due to capsule rupture or combining corneal or intraocular complications. The minimum period from PK was 12 months. All secondary IOL implantations were performed from January 2011 to August 2017. Aphakic postkeratoplasty patients were treated using one of the surgical techniques for secondary IOL implantation. In-the-bag IOL implantation was possible if the posterior capsule was complete. If the lens capsule remnants were sufficient to provide secure IOL support, an in-the-sulcus IOL implantation was performed. Scleral fixation was offered in eyes with extensive capsular deficiency or the presence of the vitreous body in anterior chamber. BCVA and expected and achieved refraction were evaluated; we included using two biometry devices, and results were compared. Results. The corrected distance visual acuity (CDVA) before surgery ranged from 0.1 to 0.8 (mean 0.54 ± 0.17). After secondary IOL implantation, CDVA ranged from 0.2 to 0.8 (mean 0.43 ± 0.14) at postoperative 1 month and from 0.3 to 0.9 (mean 0.55 ± 0.15) at postoperative 6 months (p<0.05). Comparison of the final refraction using two methods of biometry showed no statistically significant difference in the group that underwent scleral fixation of the IOL, similar to the findings for the in-the-bag and in-the-sulcus IOL implantation groups. In the scleral-fixation group, p=0.55 for the USG biometry technique and p=0.22 for the OB technique. p values for the IOL-implantation group were p=0.49 and p=0.44, respectively. Conclusion. Both implantation methods are safe for the patients. Final refraction is depending on the technique and indication to keratoplasty. Both biometry techniques deliver precise data for IOL choice.

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.

Vitreous Loss

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.

Purpose. To introduce an effective method for separating extensive posterior synechiae and those located under or adjacent to surgical incisions. Methods. Pediatric patients who had been subjected to cataract surgery and developed troublesome posterior synechiae requiring secondary intraocular lens (IOL) implantation were recruited. All patients underwent microperipheral iridectomy at the 12 o’clock position. Then, an ophthalmic viscosurgical device was injected into the posterior chamber through the iris fistula to mechanically separate the posterior synechiae, using scissors to cut robust posterior synechiae if necessary. The results of posterior synechiolysis and the position of the implanted IOL were analyzed. Results. Sixteen patients (median age, 51.56 months; range, 28–80 months) were included. The scope of posterior synechia in clock was 4.42 (range, 1–10). All troublesome posterior synechiae were successfully separated using the microperipheral iridectomy method, and all patients underwent IOL implantation in the ciliary sulcus. There was one case of peripheral iridectomy-related early intraoperative bleeding; no bleeding was observed at the end of surgery. Conclusions. Microperipheral iridectomy is a useful method for the management of troublesome posterior synechiae during secondary IOL implantation in pediatric patients, which makes secondary IOL implantation an easier and safer method in some challenging cases.

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.

Purpose: We aim to describe the clinical profile and visual outcome of paediatric patients who underwent cataract surgery in a tertiary ophthalmology referral centre in West Malaysia from 2013 to 2018. Methods: This is a retrospective review of all paediatric patients who underwent cataract surgery in our centre from 2013-2018. Results: A total of 35 eyes from 23 patients were included. There were 10 (43.5%) female and 13 (56.5%) male patients. Twelve patients (24 eyes) had bilateral cataract while 11 patients had unilateral cataract. Sixteen (45.7%) eyes had congenital cataract, followed by ectopia lentis (n=10, 28.6%), traumatic cataract (n=8, 22.9%) and steroid induced cataract (n=1, 2.8%). Three types of intraocular lens (IOL) were implanted: which were posterior chamber IOL (n=22, 62.9%), iris claw IOL (n=12, 34.3%) and scleral-fixated IOL (n=1, 2.8%). Majority of eyes (n=28, 80%) had primary IOL implantation. Twenty-five (71.4%) eyes achieved best corrected visual acuity (BCVA) of 6/12 and better at 6 months post-IOL implantation. There was no statistically significant difference in the BCVA at 6 months post-IOL implantation among the different cataract aetiology, primary or secondary IOL implantation and types of IOL implant. Eight (22.9%) eyes developed post-operative complications, which included posterior capsular opacification (PCO) (n=6, 17.1%), IOL decentration (n=4, 11.4%) and glaucoma (n=1, 2.8%). Nineteen (82.6%) patients required glasses for visual rehabilitation. Conclusion: Majority of the paediatric cataract patients achieved BCVA of 6/12 or better at 6 months post-IOL implantation. The visual outcome among the different cataract aetiology, primary or secondary IOL implantation and types of IOL implanted were similar. PCO was the most common post-operative complication.
