Abstract Details

Purpose:

To present a case series of isolated lens coloboma in young adults managed by clear lens extraction, capsular tension ring (CTR), capsular tension segment (CTS) and intraocular lens (IOL) implantation using Hoffman's corneoscleral pocket

Setting:

Advanced Eye Centre, Department of Ophthalmology, Postgraduate Institute of Medical Education and Research, Chandigarh, India

Methods:

A case series of 3 eyes of 2 patients with isolated lens coloboma. All eyes were examined for uncorrected and best corrected visual acuity (UCVA, BCVA), undilated and dilated examination of anterior and posterior segments. Pentacam was done to look for corneal regularity and astigmatism. The iTrace was done pre- and postoperatively to look for the aberrations of cornea and internal eye separately and to document visual quality. Intraocular lens power was calculated using IOL master.

Results:

Case 1: Bilateral isolated lens coloboma in 4-5 clock hours with axial myopia, with BCVA 20/30 OD with -7 DS/-3 DC × 175° and 20/80 OS with -17 DS/-4 DC × 180°. After surgery, patient achieved BCVA 20/20 OD with -1DS/ -1.75 DC × 85° and 20/30 OS with -1.25 DC × 85°. Case 2: Unilateral isolated lens coloboma in 4:30 clock hours with UCVA counting finger at 1 metre, BCVA 20/40 with -5 DC × 170°. After 3 weeks of surgery, UCVA 20/25, BCVA 20/20 with -0.5DC × 15°. There was significant improvement in visual quality on iTrace.

Conclusions:

Lens coloboma in > 4 clock hours can be safely managed with clear lens extraction, capsular tension ring, capsular tension segment and intraocular lens implantation with good postoperative refractive and cosmetic outcome with scleral fixation using Hoffman's corneoscleral pocket.
