Assessing the predictability of five intraocular lens calculation methods in eyes with prior myopic keratorefractive lenticule extraction.

Purpose: To evaluate and compare the predictability of five methods of intraocular lens (IOL) calculation in eyes with prior keratorefractive lenticule extraction (KLEx) for the treatment of myopia.

Methods: A retrospective case study included 100 eyes of 52 patients who underwent myopia and myopia with astigmatism treatment with small incision lenticule extraction (SMILE). Preoperative and 3-month postoperative measurements of optical biometry and corneal tomography were obtained.

Mechanical removal of epithelial hyperplasia leads to successful treatment of irregular astigmatism.

Background: Corneal epithelium remodeling in response to changes in the anterior corneal surface (keratoconus, corneal refractive surgery) is well-documented in the literature. However, several conditions may induce a different behavior of the epithelium, in which focal areas of epithelial thickening induce irregular astigmatism. This case report presents a highly unusual case of irregular astigmatism induced by an epithelial hyperplasia of unknown etiology, which was treated by the mechanical removal of only the epithelium.

New mechanism for epithelial ingrowth after small incision lenticule extraction: Vertical epithelial gas breakthrough.

A 41-year-old man underwent SMall Incision Lenticule Extraction (SMILE) to treat myopia in both eyes. The femtosecond procedure was uneventful but a paracentral epithelial blister appeared during the dissection of the anterior plane of the lenticule in the right eye. The posterior surface of the lenticule was dissected without any complication.

Corneal power measurements by ray tracing in eyes after small incision lenticule extraction for myopia with a combined Scheimpflug Camera-Placido disk topographer.

Purpose: To evaluate the accuracy of the measurements of corneal power obtained by ray tracing with a combined Scheimpflug camera-Placido disk corneal topographer (Sirius) in eyes after small incision lenticule extraction for myopia (SMILE).

Methods: Retrospective cases study includes 50 eyes of 50 patients who underwent myopic SMILE. Mean value of simulated keratometry (K), mean pupil power (MPP) (ray tracing, diameter of the entrance pupil range 3-6 mm), anterior and posterior corneal radius, and corneal thickness were obtained with Sirius topographer preoperatively and three months postoperatively, as well as cycloplegic refraction.

Recommendations for ophthalmologic practice during the easing of COVID-19 control measures.

In the context of the COVID-19 pandemic, this paper provides recommendations for medical eye care during the easing of control measures after lockdown. The guidelines presented are based on a literature review and consensus among all Spanish Ophthalmology Societies regarding protection measures recommended for the ophthalmologic care of patients with or without confirmed COVID-19 in outpatient, inpatient, emergency and surgery settings. We recommend that all measures be adapted to the circumstances and availability of personal protective equipment at each centre and also highlight the need to periodically update recommendations as we may need to readopt more restrictive measures depending on the local epidemiology of the virus.

Intraocular pressure changes before and after surgery for spontaneous in-the-bag intraocular lens dislocation.

Purpose: To evaluate changes in intraocular pressure (IOP) after surgical correction of spontaneous late in-the-bag intraocular lens (IOL) dislocation.

Setting: Two tertiary referral hospitals in Spain.

Design: Retrospective case series.

Laser in situ keratomileusis in patients with a history of ocular herpes.

Purpose: To report the outcomes of laser in situ keratomileusis (LASIK) in patients with a history of ocular herpes simplex virus (HSV) or herpes zoster ophthalmicus (HZO).

Setting: Clínica Baviera, Instituto Oftalmológico Europeo, Madrid, Spain.

Methods: In this retrospective case series, the records of eyes with a history of ocular herpes that had LASIK from 2003 through 2005 were reviewed.

Confocal microscopy of stage 4 diffuse lamellar keratitis with spontaneous resolution.

Purpose: To report confocal microscopic findings at the onset of stage 4 diffuse lamellar keratitis and after its resolution. Stage 4 is the most severe form of diffuse lamellar keratitis. Its incidence is approximately 1 in 5000 and is associated with stromal melting, deep flap folds, central haze, hyperopic shift, irregular astigmatism, and severe decrease in visual acuity.

Confocal microscopy in late-onset diffuse lamellar keratitis after laser in situ keratomileusis.

This article reports a case of diffuse lamellar keratitis, without exposure of the flap interface, that developed in a patient who underwent intraepithelial photorefractive keratectomy 1 year after bilateral LASIK. Confocal microscopy was performed in both eyes at the onset of the diffuse lamellar keratitis and after its resolution. In the eye with diffuse lamellar keratitis, abundant round structures (inflammatory cells) were present at the interface; these structures disappeared after the keratitis resolved and were not present in the contralateral eye at any time.
