Abstract Details

Purpose:

The purpose of this study was to assess and compare the wound integrity after stromal hydration of main and side ports and stromal hydration of only the side ports following 2.6 mm temporal uniplanar clear corneal incision phacoemulsification with implantation of foldable acrylic implant under topical anesthesia in patients with senile cataracts.

Setting:

Department of Ophthalmology, Kalra Hospital, Kirti Nagar, New Delhi, India.

Methods:

Eyes were randomly assigned to 2 groups of 30 each. Under topical anesthesia, metal blades were used to create 2.6 mm uniplanar clear corneal temporal incision and 2 uniplanar sideport incisions. Phacoemulsification with implantation of foldable lens in the bag was performed. In eyes assigned to group A , stromal hydration of main and two sideport wounds was done whereas eyes in group B had stromal hydration of only the two sideport incisions. Integrity of wound was assessed by pressing its posterior lip and Seidel test. Postoperatively, anterior segment OCT pictures were taken to assess wound apposition and any complications.

Results:

Both groups were age and sex matched. 3 (10%) eyes in group A had a small detachment of Descemet’s membrane that resolved of its own. Post hydration, firm pressure on posterior lip of main wound caused leakage in 2 (6.6%) eyes from group A that needed additional hydration, although Seidel test was negative. In group B, 2 (6.6%) eyes had inadequate apposition of right hand sideport on post-op day 1 as shown on Anterior Segment OCT (ASOCT) probably owing to damage while withdrawing the 26 Gauge cystotome. No shallow anterior chamber or post-op endophthalmitis was encountered in either group.

Conclusions:

Stromal hydration is an effective way of wound closure after clear corneal phacoemulsification surgery. Adequate hydration of sideports alone allows the main 2.6 mm wound to remain competent and water tight without any wound related complications seen till the end of 3 months follow-up.
