Article Synopsis
- The study investigated the long-term effects of combining topography-guided photorefractive keratectomy (PRK) and accelerated corneal collagen cross-linking (CXL) for treating mild-to-moderate keratoconus using a specific refractive system.
- Conducted at a tertiary eye care hospital in South India, the study involved 30 patients whose visual acuity and keratometry measurements were evaluated at multiple time points post-surgery.
- Results showed significant improvements in uncorrected and corrected distance visual acuity, as well as decreased keratometry values over 24 months, suggesting this combined procedure could be an effective treatment for early keratoconus, though further research is needed to solidify these

Purpose: To compare central corneal thickness measurements obtained by Pentacam with those obtained by IOL Master 700, Cirrus Anterior segment optical coherence tomography and Tomey Specular microscopy in normal healthy eyes.
Methods: Two hundred and six eyes of healthy subjects were included in the study. Each subject was assessed by four different methods of measuring central corneal thickness using Pentacam, IOL Master 700, Cirrus AS-OCT and Tomey Specular microscopy by a single examiner.
Purpose: Since the eye is in close proximity to the oro-nasal cavity, transmission of SARS CoV-2 is higher during ophthalmic surgical procedures, it is vital to ensure the safety of the healthcare team by pre-operative Rapid Antigen Test (RAT) and real-time Reverse Transcriptase Polymerase Chain Reaction (RT-PCR) for SARS CoV-2 viral RNA of all patients planned for elective or emergency surgery. Hence, understanding the profile of pre-operative RAT and real-time RT-PCR among patients planned for various ophthalmic procedures, will help us make better decisions for future guidelines, for optimal planning of ophthalmic elective or emergency surgeries, keeping in mind the current scenario.
Methods: This is a prospective descriptive study conducted on patients planned for elective or emergency ophthalmic surgeries, who had no COVID-19-related symptoms pre-operatively and were subjected to preoperative RAT and real-time RT-PCR of nasopharyngeal and throat swabs for SARS CoV-2 viral RNA.
Purpose: The aim of this study was to determine the frequency and various types of ophthalmic manifestation of patients with COVID-19.
Methods: This is a prospective observational study conducted on patients with SARS-Co-V-2 infection, at a dedicated tertiary COVID-19 hospital in South India from April 1 to July 31, 2020. At the time of their admission to the COVID hospital, demographic data such as name, age, sex was recorded.
