Abstract

A technique for creating a posterior capsulorhexis during phacoemulsification is presented. It can be used in cases with posterior capsule tears or opacities. The free edge of the capsule is grasped with suction using a 2 mL syringe and a 27 gauge Rycroft cannula introduced via the paracentesis. The edge is then manipulated to produce a continuous curvilinear opening in the posterior capsule. The combination of a closed eye plus the use of a viscoelastic agent in the anterior chamber and capsular bag minimizes the possibility of vitreous prolapse during the maneuver. Occlusion of the cannula tip by the posterior capsule reduces the risk of vitreous aspiration. In-the-bag intraocular lens implantation is readily achieved.

Comparison of epilenticular IOL implantation vs technique of anterior and primary posterior capsulorhexis with anterior vitrectomy in paediatric cataract surgery.

PURPOSE: To compare the functional outcome of epilenticular intraocular lens (IOL) implantation vs the technique of anterior continuous curvilinear capsulorhexis (ACCC), posterior continuous curvilinear capsulorhexis (PCCC) with vitrectomy and in-the-bag IOL implantation in paediatric cataract surgery. METHODS: Forty eyes of 33 children with developmental or traumatic cataract, whose mean age was 2-12 years, were randomly divided into two groups A and B. Group A patients underwent epilenticular IOL implantation while in group B patients, ACCC, PCCC with anterior vitrectomy with in-the-bag IOL implantation was performed. Equal number of eyes (10 each) with developmental cataracts (subgroups A1 and B1) and traumatic cataracts (subgroups A2 and B2) were allotted to both the groups. Postoperative visual acuity, opacification of the visual axis, and possible complications were observed and analysed. RESULTS: Four eyes in subgroup B2 had fibrous or ruptured capsules, and were managed by epilenticular IOL implantation technique. One eye in subgroup B2 developed central posterior capsular opacification and hence required a secondary capsulotomy. All cases in group A maintained a clear visual axis at the last follow-up. Minimal postoperative inflammation was noticed in all groups, which subsided with anti-inflammatory medication. At the last follow-up, all eyes in group A gained visual acuity >/=6/18. Whereas in group B, visual acuity >/=6/18 was obtained in 85.7% cases with the epilenticular IOL implantation technique and in 83.3% cases with ACCC and PCCC with anterior vitrectomy technique. CONCLUSION: Epilenticular IOL implantation offers a safe and effective alternative for management of paediatric cataract. In selected cases of traumatic cataract, it is the preferred treatment modality.

Completion rate of primary posterior continuous curvilinear capsulorhexis and vitreous disturbance during congenital cataract surgery.

PURPOSE: We sought to document the completion rate of primary posterior continuous curvilinear capsulorhexis during congenital cataract surgery and determine the incidence of disruption of vitreous face during this procedure. METHODS: One hundred six consecutive eyes of patients undergoing posterior continuous curvilinear capsulorhexis (PCCC) during congenital cataract surgery were evaluated prospectively for completion of PCCC and disruption of vitreous face. PCCC was performed under high-viscosity sodium hyaluronate (Healon GV 1.4%) initiated with 26 g of cystotome and later completed with Kraff-Uttrata forceps by frequent grasping and regrasping of the flap. Completion of PCCC and disruption of vitreous face during the procedure was noted. Even in cases of disrupted vitreous face, PCCC was performed and completed with forceps and, later, disruption of vitreous face was managed with 2-port automated limbal anterior vitrectomy. The size of PCCC was measured. An Alcon AcrySof SA30AL was implanted in-the-bag if the PCCC was 4 mm or smaller and in the sulcus when the PCCC was larger than 4 mm. RESULTS: The mean age of the 106 pediatric patients was 17 +/- 26 months (median, 6 months; range, 1 month to 8 years). PCCC was completed in all the eyes. Disruption of vitreous face during PCCC was noted in 5 of 106 (4.7%) eyes. The mean size of PCCC was 3.6 +/- 0.7 mm. A total of 98 (92.5%) had in-the-bag, and 8 (7.5%) eyes had sulcus implantation of IOL. CONCLUSION: PCCC was completed in all eyes with minimal disruption of vitreous face in a well-controlled manner under high-viscosity viscoelastics.
