Doi: 10.36351/pjo.v38i1.1252

Abstract

Purpose:  To evaluate the efficacy and safety of cataract extraction through small pupil with the help of a specially designed instrument called club.

Study Design:  Interventional case series.

Place and Duration of Study:  Euro eye clinic from January 2019 to December 2019.

Methods:  Seventeen consecutive patients with pupil diameter of <4mm after maximal pharmacological dilatation were recruited for study. Inclusion criteria was patients with less than 4mm pupil size after maximum pharmacological dilation. Patient with previous anterior segment surgery and small pupil with posterior synechea were excluded. The instrument (club) was originally designed for breaking posterior synechae. Sutureless Manual Extracapsular Cataract Extraction (SMECE), more commonly known as MSICS, was performed in all cases. After tunnel formation and capsulotomy, club was used to bring lens edge out in pupillary margin. Lens was then maneuvered into anterior chamber and expressed out.

Results:  All 17 patients had successful SMECE. In one patient pupil was stretched before applying instrument. None of the patients had posterior capsular rupture or hyphaema.

Conclusion:  This instrument designed in Center of Ophthalmic Instrument and Equipment Designing (COIED) is very useful, safe and cost effective. In Extra Capsular Cataract Extraction (ECCE) or SMECE, surgeons usually do keyhole iridotomy, mechanical stretching or multiple sphincterotomies for managing small pupil. With this new instrument, cataract extraction can be done without surgical trauma to the pupil, thus preserving pupil shape.
