Abstract Details

Purpose:

To evaluate the influence of postoperative eye patching after an uneventful cataract surgery on corneal edema and visual acuity.

Setting:

Public healthcare center, Assaf Harofeh Medical Center, Israel.

Methods:

A randomized controlled trial including patients who underwent an uneventful cataract surgery using phacoemulsification by two senior surgeons. Patients were randomly divided into 2 groups: The operated eye was patched at the end of the surgery for 24 hours in group 1 and only a plastic shield (without a patch) was used in group 2. Preoperative and postoperative ocular examination included: best corrected visual acuity (BCVA), cataract grading, and corneal evaluation. Anterior chamber depth (ACD), and central corneal thickness (CCT) were measured using the IOLMaster 700 (ZEISS). During the surgery cumulative dissipated energy (CDE) and operation time were recorded.

Results:

Twenty-four eyes of 24 patients aged 71.75 ± 10.27 were included in the study: 16 eyes in group 1 and 8 eyes in group 2. Postoperative increase in CCT was higher in group 1 compared to group 2; 143 µm and 49 µm respectively (p= 0.025). Post-operative BCVA was 0.49 LogMAR (Snellen equivalent 6/18) and 0.25 LogMAR (Snellen equivalent 6/12) in group 1 and 2 respectively (p=0.13). There was no difference in ACD before surgery (3.26 and 3.15; p= 0.38), and CDE (10.11 and 9.6; p=0.27) between the two groups.

Conclusions:

Postoperative eye patching after a routine cataract surgery might result in a more severe corneal edema 24 hours after surgery.
