Comparison between different tonometers following intrastromal corneal ring segments implantation.

Purpose: To compare different intraocular pressure (IOP) readings in corneas with intrastromal corneal ring segments (ICRS) taken by three different tonometers; Goldmann applanation tonometry (GAT), air puff tonometer, and ocular response analyzer (ORA) corneal-compensated IOP (ORA-IOPcc) and determine the relation of these measurements to different corneal parameters taken by Pentacam.

Methods: An observational cross-sectional analytic study included patients who underwent ICRS keraring implantation at 3 months. In each eye, the two rings were placed using the femtosecond laser assisted technique 5.

One-Year Results of Stab Incision Glaucoma Surgery and Radiofrequency-Assisted Stab Incision in Management of Open-Angle Glaucoma.

Purpose: The aim of the study is to evaluate the surgical outcome of stab incision glaucoma surgery (SIGS) and compare it with radiofrequency-assisted stab incision in the treatment of uncontrolled open-angle glaucoma.

Patients And Methods: A prospective, interventional study included 50 eyes who were assigned into two equal groups: Group A underwent stab incision procedure with preoperative subconjunctival (SC) mitomycin-C (MMC) and Group B underwent radiofrequency-assisted technique without MMC. Intraoperative and postoperative complications, visual acuity, intraocular pressure (IOP), and bleb status were evaluated up to 12 months.
