The aim of this study is to present a new method for pterygium removal using ethanol 20 % solution, applied to a retrospective consecutive case series conducted in the Department of Ophthalmology, Soroka University Medical Center, Beer-Sheva, Israel. The technique adopted the following procedure. After subconjunctival bupivacaine hydrochloride 0.5 % injection, a metal ring well, as used in laser-assisted subepithelial keratectomy, was placed above the head of the pterygium. A few drops of ethanol 20 % were applied inside the well and maintained in place for 40 s. The ethanol was then washed with Balanced Salt Solution. Pterygium was easily separated starting at 2 mm central to the head using a spatula. The apex was excised with further separation of the fibrovascular tissue towards the base. The base was excised and mitomycin C 0.02 % applied for 2.5 min. The ocular surface was profusely washed leaving the bare sclera. Records were reviewed of all the patients who underwent pterygium removal with ethanol between May 2006 and March 2007. The results showed that 68 eyes from 64 patients were operated on. There were no intraoperative complications. During follow-up periods of at least 12 months, no serious side effects were detected and only two cases (2.9 %) of recurrence were observed. The results obtained show that the Pterygium removal using alcohol 20 % solution is a simple procedure, creates a clear separation plane between the pterygium and the underlying cornea, and is a safe procedure.

Purpose: To evaluate the efficacy, safety, and outcomes of a blade- and cautery-free surgical protocol for pterygium removal.
Methods: Pterygium removal surgery was done in 69 eyes (67 patients; 24 males and 43 females) who were followed up for at least 6 months. The surgery was characterized by blunt separation of the pterygium from the head to the limbal arc using the tip of Vannas scissors and modified procedures, such as transpositional flapping and suture closure.

Purpose: Hospital and ambulatory eye surgical procedures continue to transition to the office setting. Pterygium surgery is the most commonly performed ocular surface surgical procedure in the world. No studies to date have evaluated its safety in the office-based surgical setting.

Purpose: Conjunctival autografts (CAGs) are the gold standard treatment after pterygium resection, but it is challenging to achieve consistently thin Tenon-free CAGs with manual dissection. We herein report the reproducibility and clinical outcomes of a novel algorithm to produce customizable trapezoidal CAGs using femtosecond laser (femtosecond lasers)-assisted pterygium surgery.
Methods: We first tested this algorithm in 4 pig eyes to show reproducibility.

Purpose: This study aimed to report a case of microplastics (MPs) detection in a pterygium patient's tissue.
Case Report: A pterygium specimen was obtained from the right eye of a 43-year-old woman by surgical removal of a recurred pterygium. The number, morphology, and material type of the MPs in pterygium were identified using Raman microscopy and scanning electron microscopy.

We describe a novel technique for recurrent pterygium and assess the advantage of properties of extended tenonectomy, amniotic membrane transplantation, and limbal epithelial transplantation in terms of recurrence rate, postoperative symptoms, postoperative orthoptics, and other complications. A total of nine eyes with recurrent pterygium underwent PERMISLET, i.e.
