In this review, we presented the principles of radial keratotomy (RK), its evolution, enhancement, and complications, and strategies to manage the consequences of RK in the present day. It is essential to understand the RK procedure f, the theoretical background that supported this surgery, the current effect on the cornea, and how to approach patients needing vision improvement. These patients are developing cataracts that need to be handled well, from the IOL calculation to the surgical procedure.

Purpose: This study aims to comparatively evaluate the morphological changes of the cornea after phacoemulsification (PHACO) and femtosecond laser-assisted cataract surgery (FLACS) without intercurrences in patients with type 2 diabetes mellitus.

Methods: A total of 95 diabetic patients with moderate cataracts (N2 + and N3+), 47 undergoing PHACO and 48 undergoing FLACS, were selected randomly for the study. Surgeries were performed by a single surgeon between July 2021 and December 2021.

Purpose: To evaluate the clinical performance of the Spot Vision Screener and establish clinical correlations between automated screening and retinoscopy following induction of cycloplegia in preverbal children.

Methods: In this prospective, cross-sectional study, children aged 6-36 months were evaluated using the Spot Vision Screener. A complete ophthalmologic examination, including cycloplegic refraction assessment, was performed, followed by repeat spot vision screening and retinoscopy in all cases to establish correlations regarding hypermetropia, myopia, and astigmatism following induction of induction cycloplegia.

Retinitis pigmentosa is a group of diseases caused by genetic changes that lead to progressive degeneration of photoreceptors, rods mainly. In general, it has bilateral presentation. This study is a case report of a patient with unilateral involvement of the retina, similar to the characteristics of retinitis pigmentosa, and an old ocular trauma history.

Purpose: To assess the relationship between potential visual acuity obtained before cataract surgery using Heine Lambda 100 retinometer with best corrected visual acuity 3 months postoperatively, as well as its correlation with the morphological pattern of the dominant cataract and the intensity of nuclear opacification.

Methods: Prospective study executed in the Ophthalmology Hospital Laser Vision in Santos of 121 eyes of 70 patients who underwent cataract surgery (phacoemulsification with intraocular lens implantation), from April to July, 2009. In the preoperative period, Heine retinometer test was performed under mydriasis and its results were compared to postoperative best corrected visual acuity three months after surgery and correlated with the morphological classification of cataracts, being considered a satisfactory result those who did not vary more than two lines in Snellen chart.

Purpose: To study the correlation between the signals and symptoms of dry eye in Sjögren's syndrome patients.

Methods: We formed the case group with 17 Sjögren's syndrome patients and the control group with 25 normal patients. For evaluation of the symptoms the "Ocular Surface Disease Index (OSDI)" questionnaire was applied to both groups and, after that, all the individuals were submitted to the ocular tests: Schirmer I and II, coloration of the ocular surface with rose bengal, pachymetry and esthesiometry.
