Comparing keratometry readings with manual separation of lids and wire speculum in children under general anesthesia

Indian Journal of Ophthalmology, 2021
Purpose: Keratometry (K) readings are crucial for intraocular lens power calculation in cataract surgery. In children who do not cooperate, the keratometry is done under general anesthesia with a handheld autokeratometer.

Repeatability of keratometry depending on tear film osmolarity

Acta Ophthalmologica, EarlyView.
Abstract Purpose To determine the repeatability of keratometry and astigmatism measurements of patients depending on the tear film osmolarity using three different devices. Methods In this study, 97 eyes of 97 patients with a mean age of 64.92 ± 12.07 years received three repeated measurements with the IOLMaster 700 (Carl Zeiss Meditec, Jena, Germany),

Vision‐related quality of life following trabeculectomy versus Baerveldt glaucoma implant: Five‐year results from a randomized clinical trial

Acta Ophthalmologica, EarlyView.
Abstract Purpose To assess the vision‐related quality of life (VRQoL) in glaucoma patients over 5 years after primary Baerveldt glaucoma implant (BGI) or trabeculectomy (TE) using a secondary analysis of a randomized clinical trial. Methods Patients were randomized to undergo TE or receive a BGI.
