Abstract Details

Purpose:

To assess intra-correlations between lens density based-on Scheimpflug Imaging System, power used during surgery, surgery duration, and endothelial cell loss in eyes with nuclear cataract

Setting:

Department of Ophthalmology, King Fahd Hospital of the University, Alkhobar, Saudi Arabia.

Methods:

Patients with age-related nuclear cataracts but no previous history of ocular surgery, diagnosed between April 2017 and September 2017, were enrolled in this prospective, cross-sectional, observational trial. The objective lens density and endothelial cell density were measured using the Scheimpflug system and specular microscopy, respectively. Intra-operatively, all phacodynamic parameters and duration of the surgery were documented

Results:

This study of 62 patients (71 eyes) with a mean age of 58.56 ± 10.4 years. The mean Scheimpflug-measured lens density was 13.93 ± 3.27. There were a positive linear correlations between the Scheimpflug-measured lens density and phacodynamic parameters, power (AVG %), ultrasound time, and elliptical motion (r= 0.501, r= 0.620, and r= 0.641, respectively; all P< .001), amount of endothelial loss (r= 0.445,P<.001), and surgery duration (r= 0.346;P < .01). Phacodynamic parameters were positively correlated with degree of endothelial loss (P<.01). The length of the surgery failed to show any correlation with damage happened to the endothelium (r= 0.210,P>.05)

Conclusions:

A positive correlations were observed between Scheimpflug-measured lens density with phacodynamic parameters, surgery duration, and endothelial loss. A strong correlation was observed between the degree of endothelial cell loss and phacodynamic parameters but not with the length of the procedure.
