Purpose: To report the visual outcomes and survival analysis of keratoprosthesis without contact lens wearing in a tertiary eye care hospital in Mexico City, Asociación Para Evitar La Ceguera (APEC, Coyoacán, México).
Design: Retrospective cohort with survival analysis.
Participants: Twenty-three eyes (22 patients) received KPro type 1 between 2015 and 2020 with a follow-up time of three years.
An underlying diagnosis of keratoconus (KC) can complicate cataract surgery. In this study, the results of a focused review of the literature pertaining to cataract surgery in patients with KC are detailed. Topics essential for the appropriate management of this patient population are discussed.

The new virus was taxonomically designed as Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) causing the coronavirus disease 2019 (COVID-19). SARS-CoV-2 uses the angiotensin-converting enzyme 2 (ACE2) receptor for cell invasion, which is expressed in different tissues including lungs, small intestine, testicles, kidneys, brain, and the eye.

Design: Observational cohort study.
Participants: Forty-two eyes from 41 patients with treatment-resistant infectious keratitis.
: To evaluate the efficacy of a preservative free sodium hyaluronate/chondroitin sulfate ophthalmic solution (SH/CS-PF) in patients with dry eye disease (DED).: This was a randomized phase IV, multicentric, prospective, double-blind clinical trial. Intent-to-treat (ITT) and per-protocol (PP) analyses were performed.

Materials And Methods: The translation-retro-translation method was applied to the CLDEQ-8 questionnaire. Two independent native Spanish-speaking translators adapted the questionnaire from English to Spanish, and then a committee of experienced clinicians (CE) evaluated the semantic equivalence and designed a Spanish version of the CLDEQ-8 questionnaire.
Objective: To determine the prevalence of symptoms of ocular surface disease (OSDI) surface disease and its relationship with associated risk factors in patients of ophthalmic practices using OSDI questionnaire.
Method: A cross-sectional survey was conducted Between September and December 2014 to assess the prevalence and risk factors for OSDI.
Results: The OSDI average value was 40.
To evaluate indications and outcomes of pediatric keratoplasty in a tertiary eye center, and identify factors that affect visual outcomes.We performed a retrospective review of penetrating keratoplasty in children aged 0 to 18 years between 1995 and 2011 in the Asociación para Evitar la Ceguera en México IAP, Hospital "Dr. Luis Sánchez Bulnes".

Methods: The retrospective cohort study had 152 PKPs from 152 patients. Eighteen cases were excluded from our study due to primary failure (10 cases), incomplete medical notes (5 cases) and follow-up less than 1y (3 cases).
Purpose: The purpose of this study was to ascertain the frequency and risk factors of dry eye (DE) among patients attending a tertiary care ophthalmology center in Mexico.
Methods: Approximately 338 consecutive new patients attending a tertiary care ophthalmology center in Mexico City underwent an ocular surface examination, which included tear film break-up time, fluorescein corneal staining, Schirmer's test, and evaluation of meibum quality. Symptoms of DE were evaluated by the Ocular Surface Disease Index and Dry Eye Questionnaire-5.
This retrospective report describes our 20 months'experience using intravitreal injections of bevacizumab for the treatment of several retinal diseases. We describe our experience after 1765 intravitreal injections of bevacizumab in the treatment of different proliferative retinopathies - retinopathy of prematurity, choroidal neovascularization, diabetic retinopathy, among others. We believe that the findings reported in this study move us closer to a better treatment for different pathologies.

Methods: Twenty-one eyes that had undergone LASIK were examined, all within 3 weeks to 1 month after surgery. A central scan of the total corneal thickness was obtained by using confocal microscopy in vivo.
Purpose: To determine the value of confocal and specular microscopy in the examination of corneal argyrosis in art silver solderers.
Methods: Six patients with corneal argyrosis underwent a complete physical and ophthalmologic examination. Specular microscopy was performed in three cases, and in vivo confocal microscopy in four cases.
Purpose: To report a case of a primary corneal diffuse neurofibroma in a patient with von Recklinghausen disease (NF-1).
Methods: Case report. A physical examination and histopathology were performed.
