To evaluate the incidence of posterior capsular tears (PCT) and vitreous loss (VL) during cataract surgery performed by left–handed and right–handed residents.
A retrospective chart review of 1480 eyes which were operated on for cataract extraction from July 1, 2001 to Nov 30, 2005 was conducted. The incidence of PCT and VL were analyzed in surgeries performed by left handed and right handed surgeons. All surgeries were performed by PGY 4 residents. The following variables were evaluated and: age, gender, presence of diabetes mellitus, glaucoma, small pupils, pseudoexfoliation, glaucoma, age–related macular degeneration, axial length, preoperative BCVA and history of previous intraocular surgery. The main outcomes measured were PCT and VL rates. Multiple logistic regression, student T–test, and Fisher exact tests were performed.
145/1480 (9.8%) cataract surgeries were performed by left handed residents. 1335/1480 (90.2%) were performed by right handed residents. Multiple logistic regression revealed an inverse relationship between left–handedness and incidence of PCT and VL (p=0.04, OR=0.40 and p=0.01, OR=0.08) and conversely, a proportional relationship between age and incidence of PCT and VL (p=0.02, OR=1.02 and p=0.03, OR=1.02). The incidence of PCT and VL was significantly lower in surgeries performed by left–handed residents as compared to right–handed residents (p=0.031 and <0.001).
Age and left–handedness were significant predictive factors for the incidence of PCT and VL. The incidence of PCT and VL was significantly lower in cataract surgery performed by left–handed residents.
