Filter by:Ocular injuries, a significant contributor to avoidable blindness globally, impact approximately 55 million individuals each year. Prompt initial treatment is vital for improving vision, yet the scarcity of skilled eye specialists often results in overcrowding at advanced medical centers. Moreover, the COVID-19 outbreak has introduced distinct factors into the management of ocular trauma. This research investigated the epidemiology of ocular injuries during the pandemic and offered observations on the distinctive hurdles and trends encountered.
Cellular therapy of the corneal stroma with implantation of mesenchymal stem cells derived from autologous adipose tissue with or without a carrier (scaffold) composed by decellularized human donor corneal stroma is used in patients with corneal diseases such as corneal dystrophies, and keratoconus. For this purpose, the study planned to assess the enhancement of visual acuity, pachymetric, and aberrometric parameters with implantation of autologous mesenchymal adipose tissue-derived adult stem cells (ADASCs) alone, 120 µm thickness of decellularized or recellularized laminas with ADASCs. Three groups will be included in the study: (1) Implantation of a single dose of ADASCs alone without scaffold. (2) Implantation of decellularized human corneal lamina without ADASCs. (3) Implantation of the recellularized human corneal lamina with ADASCs.
Purpose: The aim of the study was to compare the analgetic effect of two solutions of intracameral anesthesia in patients undergoing cataract surgery and assess the factors influencing the patients' postoperative activities. Methods: In this prospective, single-blind, randomized study, a group of 62 patients undergoing cataract surgery received Mydrane (Mydrane group) or a combination of 1% solution of lignocaine and 0.025% solution of adrenalin (reference group) as an intraocular anesthetic. The analgetic effect of these two anesthetic methods was evaluated using psychological tools - Visual Analog Scale for Pain (VAS Pain) and Brief Pain Inventory-short form (BPI) on the next day after the surgery.
The study is a Randomized Intervention, Multi-Center Study to Determine the Role of Fatty Acids in Serum and Breast Milk in preventing Retinopathy of Prematurity Subjects who meet all inclusion and none of the exclusion criteria will be enrolled into the study. Upon entry into the study, subjects will be randomized and given a unique subject number. A randomized intervention study of 105+105 (number based on power analysis regarding up to date ROP frequency, see 5.1 and 11.1) infants without major malformations born with a gestational age less than 28 weeks + 0 days will be performed.
To determine whether the implantation of an intrastromal corneal ring is an effective treatment for a homogeneous group of mild keratoconus patients.
