In this review, we analyzed the domestic and foreign literature on use of corneal lenticula obtained by keratorefractive surgery using SMILE technology (SMall Incision Lenticula Extraction). Research is being actively carried out a lenticular tissue for refractive purposes: correction hyperopia (LIKE – Lenticular Intrastromal Keratoplasty), presbyopia (PEARL PrEsbyopic Allogenic Refractive Lent...

BACKGROUND The purpose of this case series is to evaluate the safety and efficacy of VisuMax® Circle patterns in eyes that have undergone small incision lenticule extraction, thus creating a flap to perform an enhancement procedure or residual lenticule extraction. METHODS This prospective, single center, case study series evaluated the use of a VisuMax® Circle pattern to create a corneal fla...

The surgical indication for Descemet-stripping automated endothelial keratoplasty (DSAEK) is largely limited to phakic or pseudophakic cases of endothelial dysfunction with normal pupils, because the endothelial lenticule is generally attached to the recipient cornea by use of gas tamponade into the anterior chamber. Although it may be desirable for vitrectomized cases with aniridia and aphakic...

PURPOSE To evaluate the 5-year results of femtosecond laser-assisted refractive lenticule extraction (ReLEx-FLEx) for the treatment of myopia and myopic astigmatism. SETTING Departments of Ophthalmology, Helios Klinikum Erfurt, Erfurt, and Phillips Universität Marburg, Marburg, Germany. DESIGN Prospective clinical trial. METHODS This was a follow-up of a prospective study that evaluated t...

Presbyopia remains a major visual impairment for patients, who have previously undergone laser refractive correction and enjoyed unaided distance vision prior to the onset of presbyopia. Corneal stromal volume restoration through small incision lenticule extraction (SMILE) lenticule re-implantation presents an opportunity for restoring the patients' non-dominant eye to previous low myopia to ac...

PURPOSE To assess and compare keratocyte viability and collagen structure in cornea stroma lenticules collected immediately after refractive lenticule extraction (ReLEx) and one month after cryopreservation. METHODS The fresh and cryopreserved human stroma lenticules procured after ReLEx were processed for ultrastructural analysis of keratocytes and collagen fibrils with transmission electron...

BACKGROUND To introduce the Chung's swing technique for small-incision lenticule extraction (SMILE). METHODS A total of 112 eyes of 56 patients were included in this study. Patients were divided into two groups: 52 eyes of 26 patients were treated with SMILE using a traditional method (traditional group) and 60 eyes of 30 patients were treated with SMILE using the Chung's swing technique (swi...

We wanted to congratulate Ng et al.1 for describing an effective lenticular hydration technique for identification and extraction of a lenticular remnant after small incision lenticule extraction (SMILE). We also agree with their observation that prevention is the best solution for this condition and we would like to add here two techniques described by one of us (SJ) to facilitate easy extract...

PURPOSE The purpose of the study was to determine the accuracy of intraocular pressure (IOP) measurement after small incision lenticule extraction (SMILE) using Goldmann applanation tonometry (GAT) and ocular response analyzer (ORA). METHODS This is a prospective clinical study that was conducted on 30 eyes in the interval between February 2016 and September 2016. The age of the patients rang...

PURPOSE Lenticule implantation can be used to correct vision problems. However, it is significantly restrained by the sources of autologous lenticules. The aim of the present study was to investigate the feasibility and effects of femtosecond laser-assisted corneal small incision allogenic intrastromal lenticule implantation (AILI) in monkeys. METHODS Six healthy adult monkeys were included i...
