Abstract:
Strong evidence suggests that corneal crosslinking is a safe procedure capable of stopping or slowing down the progression of keratoconus, avoiding visual loss associated with progression, and delaying or preventing the need for corneal t…
Purpose:
The purpose of this study was to describe the feasibility of Descemet membrane endothelial keratoplasty (DMEK) as a treatment modality for spontaneous detachment of DM (DMD) decades after penetrating keratoplasty (PK) for keratoconus.

Purpose:
The aim of this study was to investigate the reliability of subbasal corneal nerve plexus parameters of the inferior whorl compared with the central cornea with in vivo corneal confocal microscopy and to investigate the impact of inferior …
Purpose:
This study describes the surgical outcomes of selective endothelialectomy in Peters anomaly (SEPA), a relatively new technique to manage Peters anomaly (PA).
Methods:
This study included 34 eyes of 28 children who had a visually significant posterior corneal defect due to PA and underwent SEPA between 2012 and 2019. A selective endothelialectomy from the posterior corneal defect was performed while preserving Descemet membrane. The primary outcome measure was the resolution of corneal opacification. The secondary outcome measures were functional vision, complications, and risk factors for failure.
Results:
At a mean postoperative follow-up of 0.96 ± 0.20 years, 29 eyes (85.3%) maintained a successful outcome. Mean preoperative and postoperative best-corrected visual acuities were 2.55 ± 0.13 and 1.78 ± 0.13 (P
Purpose:

Purpose:
The purpose of this study was to report the 2-year outcomes of a double-blinded randomized controlled trial comparing Descemet membrane endothelial keratoplasty (DMEK) and microthin Descemet stripping automated endothelial keratoplasty (MT…
Purpose:
The purpose of this study was to report a serious complication of early sterile keratolysis associated with a presbyopia inlay implantation combined with hyperopic laser in situ keratomileusis (LASIK).
Methods:
A 55-year-old hyperop…
Purpose:
Circular RNAs (circRNAs) are a novel class of endogenous noncoding RNAs that regulate gene expression through the competitive endogenous RNA (ceRNA) mechanism. CircRNA-associated-ceRNA networks are closely related to oxidative stress–relat…
Purpose:
To assess the changes in the posterior corneal curvature after pre-Descemet’s endothelial keratoplasty (PDEK) and correlate with the visual outcomes.
Methods:
Eyes with pseudophakic bullous keratopathy, aphakic bullous keratopathy, and Fuchs dystrophy undergoing PDEK were included. The main outcome measures were the topography (OrbscanIIz, Bausch and Lomb) indices—total corneal power (TCP) in diopters (D), radius of the posterior curvature (mm), and best-fit sphere of the posterior corneal surface (BFS in D) at preoperative and postoperative 1 month, 3 months, and 6 months.
Results:
Overall, 43 eyes of 43 patients with a mean age of 68 ± 9.6 years were studied. The mean preoperative TCP 43.1 D ± 2.3 reduced to 42.4 D ± 2.6 at 3 months (P 0.05). The mean BFS showed an increase at 1 month (53.45 ± 5.2 D) and 3 months (52.95 ± 5.1 D) and decrease at 6 months (51.90 ± 5.3 D). The overall change in BFS (P > 0.05) was not significant. There was significant improvement in visual acuity (P
