Hannuy, Youngsub, Su-Yeon, Jong, and Hyo: Incidence of Complications in Cataract Surgery according to the Availability of Partial Coherence Laser Interferometry

Abstract

Purpose

To validate the possibility of IOLMaster measurement as a predictor of intraoperative and postoperative complications during phacoemulsification surgery.

Methods

In this study, 2,107 eyes from 1,456 patients who underwent phacoemulsification with intraocular lens (IOL) im-plantation were divided into two groups according to the possibility of performing optical biometry with the IOLMaster (measurable group: 1,746 eyes from 1,141 patients, unmeasurable group: 361 eyes from 315 patients). The intraoperative and postoperative complication rates were compared between the two groups.

Results

Three hundred sixty-one eyes (17.1%) could not be measured using optical biometry. Dense posterior subcapsular cat-aract (56.0%) was the main factor resulting in failed measurements with optical biometry, followed by anterior subcapsular cata-ract (12.5%). The rates of posterior capsule rupture and radial tear were significantly higher in the unmeasurable group than in the measurable group (p = 0.001, p < 0.001, respectively). Corneal edema was significantly higher in the unmeasurable group (16.1%) than in the measurable group (5.3%) at postoperative 1 week (p < 0.001).

Conclusions

Possibility of optical biometry measurement can be used as a simple predictor of intraoperative and postoperative complications of phacoemulsification surgery. Surgeons should pay close attention to patients who cannot be measured using IOLMaster.
