Boston Keratoprosthesis type 1 (KPro) without contact lens wearing in end-stage corneal disease: The APEC experience.

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.

Early keratometric and refractive results after intra-corneal rings surgery in keratoconus patients.

Objective: To evaluate early keratometric and refractive results after intra-corneal rings surgery in keratoconus patients.

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.

Pars plana vitrectomy and therapeutic keratoplasty in endophthalmitis and infectious keratitis.

Purpose: To describe the anatomical and functional outcomes of patients with infectious keratitis (IK) and secondary endophthalmitis who underwent penetrating keratoplasty (PK) after pars plana vitrectomy (PPV) assisted by temporary keratoprosthesis (TKP).

Methods: An observational retrospective case series was performed. Data were collected from January 2013 to July 2020.
