Management and Outcomes of Traumatic Cataract During Open Globe Repair

Abstract

PurposeTo compare outcomes of primary lensectomy (PL) versus no lensectomy (NL) during repair of zone I (involving cornea and limbus) and II (up to 5mm posterior to the limbus) ruptured globe injuries (RGIs) with lens involvement. DesignRetrospective clinical cohort study. Methods107 patients with RGIs involving both blunt and penetrating injury to the lens who presented to Wills Eye Hospital between April 1, 2017 and August 31, 2022 were included. Data from presenting visit was collected including demographic information, time from injury to surgery, visual acuity (VA), intraocular pressure (IOP), injury characteristics, and years since residency graduation of surgeon. VA, IOP, retinal detachment (RD) rate, and endophthalmitis incidence were compared between PL and NL groups at postoperative week 1 (POW1) and postoperative month 1 (POM1). VA, peak IOP, need for further surgeries, and types of additional surgery were compared between the two groups at the final visit. Results19 (17.8%) patients underwent PL. Age, sex, and initial VA were similar between groups (all p≥0.05). The PL group had surgery later from the time of injury (6.1±14.6 days vs. 1.3±1.9 days; p=0.010), higher IOP at presentation (12.9±11.6 mmHg vs. 7.7±11.3 mmHg; p=0.046), shorter wounds (2.3±1.4mm vs. 4.7±3.2mm; p=0.003), more frequent lens capsule violation (89.5% vs. 50%; p=0.010), increased likelihood of intraocular foreign bodies (52.6% vs. 17.0%; p=0.004), and were more likely to be operated on by surgeons with ≥ 5 years of experience post-residency (68.4% vs. 28.4%; p<0.001). At POW1, the PL group had significantly better logMAR VA (1.2±0.9 vs. 2.0±1.0; p=0.002), and this continued at POM1 (1.0±0.8 vs. 1.6±1.1; p=0.031) and the final visit (0.4±0.7 vs. 1.0±1.1; p=0.010). The PL group had lower IOP at POW1 (12.4±3.0 mmHg vs. 17.3±8.2 mmHg; p=0.005) than the NL group. There was no difference in RD or endophthalmitis rates between the two groups at POW1 or POM1 (p>0.05 for all). The NL group was more likely to require additional surgery by final follow-up (77.3% vs. 47.4%; p<0.001). In the multivariable analysis, PL had better final VA and decreased need for further surgery (both p<0.05). ConclusionsIn the appropriate circumstance, PL during lens-involving anterior RGI repair may lead to improved patient outcomes.
