Article Synopsis
- The study evaluates how well the Ocular Surface Disease Index (OSDI) and the Symptom Assessment iN Dry Eye (SANDE) questionnaires work together in assessing dry eye disease (DED) in a diverse patient population across Mexico.
- Involving 3,421 patients, the results showed a significant correlation between the two questionnaires, indicating they can be used complementarily to assess symptoms more reliably.
- The findings suggest both questionnaires effectively measure DED symptoms with improved overall reliability when used together, signaling their potential interchangeability in clinical settings.
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.

Method: 50 eyes of 25 patients with keratoconus within stage 2 and 3, underwent intra-stromal corneal rings surgery by using the femtosecond surgical laser, one month after surgery, corneal keratometries and patient refraction were compared vs pre-operative ones.
Results: Mean pre-operative low keratometry was 48.
Dry eye disease (DED) has a higher prevalence than many important systemic disorders like cardiovascular disease and diabetes mellitus, representing a significant quality of life burden for the affected patients. It is a common reason for consultation in general eye clinics worldwide. Nowadays, the diagnostic and therapeutic approach at the high corneal and ocular surface specialty level should be reserved for cases of severe and chronic dry eye disease associated with systemic autoimmune diseases or complicated corneal and ocular surface pathologies.

Methods: In MYSTIC (NCT03873246) patients aged ≥22 years with dry eye disease were randomized 1:1:1 to OC-01 0.
Purpose: The purpose of this study was to report a case of bilateral ectasia 3 years after small incision lenticule extraction (SMILE) in a patient with normal preoperative topography of the right eye and abnormal topography of the left eye.
Methods: This study was a case report.
Results: A 22-year-old man developed bilateral corneal ectasia after SMILE.
Objective: To evaluate confocal microscopy finding after SMILE surgery by in vivo confocal microscopy and stromal lenticule and stromal interface accuracy planed vs measured.
Method: Thirty eyes of 15 patients were evaluated before and 1 month after SMILE surgery by using confocal microscopy. Cellular morphology was studied.
Purpose: To present a case series of non-healing corneal ulcers treated by solid activated platelet-rich plasma (PRP) combined with silicone-hydrogel soft contact lens.
Methods: Three eyes from three patients with unresponsive corneal ulcers were included. A clot of PRP was applied directly onto the corneal ulcer and covered with a soft contact lens.
Objective: To describe clinical characteristics, complications, and the most prevalent microorganisms causing polymicrobial keratitis and their antibiotic sensitivities.
Methods: A cross-sectional study including a consecutive analysis of patient's records with a diagnosis of bacterial keratitis with a positive culture and antibiogram report were included. Patients were grouped into those having monomicrobial and polymicrobial infection.
Purpose: To investigate the efficacy of photoactivated chromophore corneal collagen cross-linking (PACK)-CXL in the management of treatment-resistant infectious keratitis.
Design: Observational cohort study.
Participants: Forty-two eyes from 41 patients with treatment-resistant infectious keratitis.
Purpose: To report the in vivo confocal microscopy (IVCM) findings of a case who underwent femtosecond laser-assisted Bowman layer transplantation (BLT).
Methods: This is a case report.
Results: In a 25-year-old man with previous diagnosis of keratoconus in whom a BLT was performed using the femtosecond laser-assisted technique, IVCM (Confoscan 4; Fortune Technologies, Vigonza, Italy) was performed 3 months after surgery, obtaining a sequence of 4 digitalized images of the total thickness of the cornea, from the epithelium to the endothelium, and then backward.
Purpose: To determine genetic mutational profiles in patients with Ocular Surface Squamous Neoplasia (OSSN) using whole exome sequencing.
Methods: Prospective, case-series study. Patient recruitment was conducted in a single tertiary referral center from April to September 2017.

Purpose: To determine whether sole full-thickness corneal sutures are a feasible treatment for acute corneal hydrops, and if so, report the anatomic and visual results of this technique.
Methods: A retrospective case series was carried out in 17 patients, all of whom received sole full-thickness sutures as a treatment for corneal hydrops.
Results: The included patients reported symptom commencement a median of 15 days before the surgical intervention.
Background: Meibography is a diagnostic test that allows in vivo evaluation of meibomian gland (MG). Nowadays, it is unknown whether the two available computer programs are equivalent to evaluate the glandular loss area.
Methods: This is a prospective, longitudinal, and observational study.
Purpose: We describe the functioning of a novel device, aimed to assess patient head position after a pneumatic retinopexy.
Methods: We enrolled patients with the clinical diagnosis of rhegmatogenous retinal detachment. All patients were asked to wear a specially designed headband with a monitoring device composed of an accelerometer, gyroscope, and magnetometer, powered by a 3.
We describe a variation of the original manual Bowman layer transplantation technique. After the isolation of the graft, a stromal pocket is created using a femtosecond laser. With the use of this technology, which entails preservation of the conjunctiva and the non-use of sutures, we avoid the scleral approach.

Methods: Based on the MAPI Institute guidelines, the linguistic validation procedures consisted of four steps. Every step was reviewed by the committee.
Purpose: To analyze potential risk factors for ocular surface damage in a representative population of Mexican patients with dry eye disease (DED).
Patients And Methods: A prospective and cross-sectional population-based epidemiologic cohort study was conducted through a survey of patients with symptoms, signs, known preexisting diagnosis, and clinical conditions related to DED. Fluorescein staining, tear break-up time (TBUT), and Oxford lissamine green staining were performed on both eyes of patients enrolled in the study.
Purpose: To present the process of cultural and psychometric adaptation, and clinical validation of a new version in the Spanish language of the Contact Lens Dry Eye Questionnaire-8 (CLDEQ-8).
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 evaluate early in vivo corneal wound healing findings after Descemet's Stripping Automated Endothelial Keratoplasty (DSAEK) by using in vivo confocal microscopy.
Method: A total of 15 eyes of 15 patients were included. In vivo confocal microscopy (Confoscan 4, Fortune Technologies, Italy) was performed from 4 to 7 weeks after DSAEK.
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.
