Surgeons should use their chosen intraocular lens (IOL) measurement method when performing cataract surgery with endocyclophotocoagulation (ECP). There is no need to adjust the IOL power because this operation has no effect on the refractive outcome.

The purpose of this study was to compare postoperative refractive outcomes in patients with glaucoma who underwent phacoemulsification and IOL implantation with or without ECP and the change in intraocular pressure (IOP) and number of antiglaucoma medications between groups.

The medical records of patients with any form of glaucoma who had phacoemulsification with IOL implantation in the capsular bag in addition to ECP or as a standalone procedure were examined in this cross-sectional analysis.

Axial duration, steep, flat, and mean keratometry values, target spherical equivalent (SE) calculated by the SRK/T formula, manifest refraction SE at the 1-month follow-up, IOP, and number of antiglaucoma medications were among the clinical data collected before and after surgery.

Primary and secondary outcome measures were the mean predictive error (MPE), the postoperative SE, and the change in IOP after surgery in both groups, respectively. Significance was assessed using the Student t test for all variables between groups according to data distribution.

Results:
--A total of 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, and 0.06±0.38D MPE, respectively.

--Overall, 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 a greater decrease in antiglaucoma medications at 12 months of follow-up.

Finally, the SRK/T formula worked well in both classes, with no statistically significant differences in MPE or the proportion of eyes with a postoperative SE of ±0.50. When conducting ECP, researchers believe that some kind of adjustment to the IOL power calculation is unnecessary.
