ABSTRACT Femtolasik is one of the most used techniques in refractive surgery due to good refractive results, predictability, reproducibility, and safety, achieving excellent results and a high degree of satisfaction. Although the complication rates are small, it is worth noting that there may be intercurrences. The objective of this work is to report a case of complication in the dissection of the lamella of laser in situ keratomileusis (Lasik) with Femtosecond laser, and subsequent lamella tear. Excimer Laser was applied […]

ABSTRACT Implantation of phakic intraocular lenses for refractive purpose is a safe and efficient elective surgical alternative. This option should be considered to electively treat ametropia when laser corneal refractive surgery has higher risk of complications, either due to corneal characteristics or the magnitude of ametropia. This article provides a prospective review of the phakic lenses available in the Brazilian market in 2020 and their characteristics.

ABSTRACT The laser in situ keratomileusis (LASIK) is the most widely used refractory surgical method in the world with excellent results, but this method is not without risks. Post-LASIK ectasia is a serious complication and is characterized by a progressive increase in curvature and thinning of the cornea, resulting in irregular astigmatism and decreasing visual acuity. Its incidence in the current literature is approximately 0.033%. The main treatment for this complication is the implantation of an intra-stromal ring with crosslinking. […]

Abstract Cataract surgery with intraocular lens implantation is one of the most commonly performed surgeries in the world and, currently, patients who undergo this surgery can use the multifocal intraocular lens (IOL) implant as an alternative to wearing glasses. A great challenge for the surgeon are patients who have previously undergone radial keratotomy (RK), because in addition to having a more challenging biometric calculation, they also have important corneal optical aberrations, being a contraindication for the use of multifocal lenses […]

Abstract Objectives: Toassess the satisfaction of patients undergoing central Presbilasik surgery and to determine the age of patients who undergo PresbiLASIK and the prevalence of symptoms reported after surgery. Methods: This is a descriptive, observational, cross-sectional study with data collected from patients previously submitted to PresbiLASIK. Results: The sample consisted of 45 patients, with a mean age of 57.7 (±7,19) years. The average score attributed to visual satisfaction with the procedure was 8.9 (±1.0). Visual quality after surgery was classified […]

This article presents a review of the principles and clinical applications of the Scheimpflug principle in the anterior segment imaging. By providing a three-dimensional image of the anterior segment, this technology provides elevation and curvature data of the anterior and posterior surfaces of the cornea, pachymetric mapping, the total refractive power of the cornea and the anterior segment biometry. For the refractive surgery sub-specialty, this approach improves the ability to identify cases at risk of ectasia, as well as the […]
