Clinical results of management of aphakia with Soemmering ring in microcornea.

Abstract

Purpose: To present clinical outcomes of glued IOL scaffold for management of aphakia with Soemmering ring in eyes with microcornea.

Design: Prospective, Interventional series.

Setting: Private practice.

Methods: 11 eyes of 6 patients (3 males, 3 females) with microcornea underwent glued IOL scaffold procedure for aphakia associated with Soemmering ring. All patients had undergone initial cataract surgery at age less than 10 years and were rendered aphakic.

Main outcome measures: Uncorrected and best-corrected visual acuity (UCVA; BCVA), Specular count and IOL centration.

Results: The mean age group of the cases was 22.9±11years, the mean corneal diameter was 7.8±0.25mm, the mean axial length was 21.7±1.2mm and the mean extent of Soemmering ring was 5.2±2.4 (range 3-10) clock hours. The mean follow-up period was 31.6±16.8 months. The mean preoperative and postoperative UCVA was 1.64±0.15 LogMAR and 0.68±0.18 LogMAR respectively (p=0.003). The preoperative and postoperative specular count was 2463.4±451.3 cells/sq mm and 2264.5±459.4 cells/sq mm respectively. The mean percentage of endothelial cell loss was 8.3±4.8%. The mean haptic length trimmed was 1.3±0.17mm and all the haptics were well-placed in subscleral position. Negative correlation was observed between the corneal diameter and the extent of haptic length trim. The IOL was well-centred in all the cases and there was no incidence of slippage of soemmering material into the vitreous cavity.

Conclusions: Satisfactory visual outcomes can be achieved in eyes with microcornea and aphakia with associated soemmering ring.
