Refractive Outcomes of Cataract Surgery With or Without Endocyclophotocoagulation.

Abstract：

PRECIS:Surgeons that perform cataract surgery combined with endocyclophotocoagulation should rely on their preferred IOL calculation formula. There is no need to perform any correction to the IOL power, as this procedure does not modify the refractive outcome. PURPOSE:To compare postoperative refractive outcomes in patients with glaucoma who underwent phacoemulsification and intraocular lens (IOL) implantation with or without endocyclophotocoagulation (ECP) and the change in intraocular pressure (IOP) and number of anti-glaucoma medications between groups. METHODS:Cross sectional study in which the medical records of the patients with any type of glaucoma, who underwent phacoemulsification with IOL implantation in the capsular bag in addition to ECP or as a standalone procedure from June 2016 to August 2019 were analyzed. Clinical data collected included axial-length, steep, flat and mean keratometry values, target spherical equivalent (SE) estimated by the SRK/T formula, manifest refraction SE at the one-month follow-up, IOP and number of anti-glaucoma medications before and 12 months after surgery. Primary and secondary outcome measures were the mean predictive error (MPE), the postoperative spherical equivalent and the change in IOP after surgery in both groups respectively. Significance was assessed using the t-student for all variables between groups according to data distribution. P values < 0.05 were considered to be statistically significant. RESULTS:196 eyes of 196 patients were included, 98 in the combined phacoemulsification- ECP group and 98 in the non-ECP group. The observed MPE was -0.043±0.44 D, and 0.06±0.38 D MPE respectively (P=0.079). 74.34% in the phacoemulsification-ECP group and 78.4% in the non-ECP group had a postoperative SE of ±0.50. The ECP group had lower IOP and greater decrease in anti-glaucoma medications at 12 months follow up. CONCLUSIONS:SRK/T formula performed well in both groups, with no statistically significant difference in the MPE and in the percentage of eyes achieving postoperative SE of ±0.50. We consider it is unnecessary to perform any kind of correction to the IOL power calculation when performing ECP.
