Article Synopsis
- - The study aimed to assess treatment choices and outcomes for keratoconus by analyzing medical records of 1162 patients and categorizing them based on the CLEK Study grades, focusing on best-corrected visual acuity (BCVA) and topographic data.
- - Results indicated that nonsurgical management was prevalent in patients with less severe corneal steepness (K<52 D), while surgical interventions were more common in advanced cases (K>60 D), with significant overall improvements in BCVA after treatment.
- - Steep K was identified as a critical factor influencing treatment decisions and outcomes, particularly highlighting the need for different approaches based on the severity of the disease.
Aim: To compare long-term postoperative outcomes of manual and femtosecond assisted corneal trephination in deep anterior lamellar keratoplasty (FS-DALK) for keratoconus.
Methods: In the retrospective study, 17 consecutive eyes that underwent vertical side cut incision FS-DALK and 22 eyes that underwent trephine incision DALK were collected over a 2-year period. Main measurements included postoperative uncorrected-visual acuity (UCVA), corrected distance visual acuity (CDVA), refractive sphere and cylinder, manifest refraction spherical equivalent (MRSE), flat and steep corneal keratometry (K1 and K2), endothelial cell density (ECD), and time of epithelium healing and suture removal.

Aim: To evaluate the diagnostic efficiency of basic indicators and find characteristic indicators for keratoconus (KC) at adjacent stages, and to assess the progression pattern of KC.
Methods: One hundred and eight (41 subclinical, 40 moderate, and 27 severe) keratoconic patients (108 eyes) and 105 myopic patients (105 eyes) as controls were recruited in this prospective, comparative case series study. Pentacam topography was performed.
Cryptochromes are suggested to be involved in the bird magnetoreception based on the radical pair mechanism (RPM), a well established theory of weak magnetic field effects on chemical reactions. Two members of cryptochrome/photolyase family were found to respond to magnetic field, however, no direct responses of bird cryptochrome to magnetic field as weak as the Earth's magnetic field have been obtained so far. In this study, we used transient fluorescence spectroscopy to characterize the weak magnetic field effects of bird cryptochromes.

Objective: To compare the sensitivity of Pentacam and OrbscanII and to analyze the morphology characteristic of topography in normal eyes and different stages of keratoconus, to provide the basis for early screening of keratoconus suspects.
Methods: One hundred and ninety six normal eyes, 50 eyes with keratoconus suspect and 73 eyes with clinical keratoconus were enrolled. The changes of corneal anterior/posterior curvature, best fitting sphere (BFS).
