Combination of capsular tension ring and capsular tension segment for the management of lens coloboma >4 clock hours

Lens colobomas extending more than 4 clock hours and causing visual impairment require lens extraction along with capsular support devices with scleral fixation for adequate centration of the capsular bag and for prevention of capsular fornix aspiration with inadvertent extension of zonular dialysis intraoperatively. In this case series, we describe a technique for the management of isolated lens colobomas involving 4–5 clock hours by clear lens extraction and intraocular lens implantation using a combination of a capsular tension ring with a capsular tension segment (CTS) for the centration and stability of the capsular bag. Hoffman's corneoscleral pocket and half-bow sliding knot technique were used for scleral fixation of the CTS.

Optic Capture in a patient with Congenital Lens Coloboma

PURPOSE: To report the effect of the optic capture in the treatment of congenital lens coloboma. METHODS: A 5-year old boy was transferred to Maryknoll Hospital with congenital lens coloboma in his right eye. Lens coloboma at superotemporal area and capsular cataract around the coloboma was observed in the slit lamp examination. Posterior continuous curvillinear capsulorrhexis was performed after irrigation and aspiration of the lens. Optic was captured behind the posterior capsule while its haptics were placed in the sulcus. RESULTS: Best corrected visual acuity improved from preoperative 20/63 to 20/20 postoperatively. Intraocular lens decentration and rotation and other sight threatening complications were not found during the follow up period. CONCLUSIONS: Optic capture is thought to be a safe and effective means to prevent IOL decentration and posterior capsular opacity in the treatment of congenital lens colobomas.

A Case of Retinal Detachment Associated with Lens Coloboma

Rarely, break in the non-pigmented epithelium in the pars plicata can occur and sometimes develop into retinal detachment. We experienced a case of retinal detachment associated with lens coloboma in 34-year-old male. A break in the non-pigmented epithelium in pars plicata was found with retinal detachment. We treated the break by cryoapplication, scleral buckling and encircling.

A Case of Congenital Aniridia

Aniridia, a condition which shows only an extremely rudimentary iris, is a re latively rare congenital anomaly. It is almost bilateral and occurs as an autosomal dominant trait. The authors experienced one patient who had congenital aniridia combined with cataract, ectopia lentis, lens coloboma, corneal opacity and nystagmus in both eye. Intracapsular cataract extraction was performed with satisfactory result. The authors report this case with the review of literatures.
