AI Article Synopsis
- The study aimed to assess the impact of combined femtosecond laser-assisted excimer laser keratomileusis (FS-LASIK) and accelerated corneal cross-linking (FS-LASIK Xtra) on corneal densitometry in patients with high myopia.
- A total of 130 patients who underwent either FS-LASIK or FS-LASIK Xtra were evaluated at multiple points (1, 3, and 6 months post-surgery) for corneal densitometry using advanced imaging techniques.
- Results showed significant differences in corneal densitometry favoring the FS-LASIK Xtra group during the early months post-surgery, but by 6 months, the densit
Article Abstract
Aim: To observe the effects of femtosecond laser-assisted excimer laser keratomileusis combined with accelerated corneal cross-linking (FS-LASIK Xtra) on corneal densitometry after correcting for high myopia.
Methods: In this prospectively study, 130 patients underwent FS-LASIK or FS-LASIK Xtra for high myopia. Their right eyes were selected for inclusion in the study, of which 65 cases of 65 eyes in the FS-LASIK group, 65 patients with 65 eyes in the FS-LASIK Xtra group. Patients were evaluated for corneal densitometry at 1, 3, and 6mo postoperatively using Pentacam Scheimpflug imaging.
Results: Preoperative differences in corneal densitometry between the FS-LASIK and FS-LASIK Xtra groups in different ranges were not statistically significant (>0.05). Layer-by-layer analysis revealed statistically significant differences in the anterior (120 µm), central, and total layer corneal densitometry between the FS-LASIK and FS-LASIK Xtra groups at 1 and 3mo postoperatively (all <0.05), the FS-LASIK Xtra group is higher than that of the FS-LASIK group. Analysis of different diameter ranges showed statistically significant differences between the FS-LASIK group and the FS-LASIK Xtra group at 1mo postoperatively in the ranges of 0-2, 2-6, and 6-10 mm (both <0.05); At 3mo postoperatively, the FS-LASIK Xtra group is higher than that of the FS-LASIK group in the ranges of 0-2 and 2-6 mm (<0.05). At 6mo postoperatively, there were no statistically significant differences in corneal densitometry between the FS-LASIK group and the FS-LASIK Xtra group in different diameter ranges (all >0.05).
Conclusion: There is an increase in internal corneal densitometry during the early postoperative period after FS-LASIK Xtra for correction of high myopia. However, the densitometry values decreased to the level of conventional FS-LASIK at 6mo after surgery, with the most significant changes observed in the superficial central zone.

Ophthalmology, Hoopes Vision, Draper, USA.
Purpose: The aim is to assess for any lasting changes in corneal densitometry (CD) in patients who underwent small incision lenticule extraction (SMILE) and developed early transient postoperative corneal haze.
Methods: This retrospective chart review analyzed 98 eyes from 49 patients who underwent SMILE at the Hoopes Vision Clinic and had one-year postoperative Pentacam CD (Oculus Optikgeräte GmbH, Wetzlar, Germany). These were compared to 78 eyes from 42 unoperated myopic control patients with documented CD measurements.

Purpose: To compare corneal aberrometry, densitometry, and refractive outcomes of single-step Transepithelial Photorefractive Keratectomy (Trans-PRK) with and without epithelial thickness customization.
Patients And Methods: This was a prospective, interventional, randomized controlled study. Patients undergoing Trans-PRK using the WaveLight EX500 laser with StreamLight software (Alcon Laboratories, Forth Worth, TX, USA) were randomly assigned to control (55 µm standard epithelial thickness) or customized (thinnest point of epithelial thickness for each patient) groups.

Article Synopsis
- Fuchs endothelial corneal dystrophy (FECD) is a genetic and age-related disease leading to the loss of corneal endothelial cells, resulting in corneal swelling and vision issues.
- Advanced FECD often shows a fibrillar layer (FL) on the corneal surface, especially in the inferotemporal quadrant, which can be measured using specialized imaging techniques.
- Current treatments mainly involve corneal transplantation, particularly DMEK surgery, with new approaches like smaller grafts and advancements in imaging for better assessment and planning of surgeries.

Corneal densitometry (CD) uses the biological properties of the cornea to visualize the morphology of the cornea and determine the degree of corneal transparency. At present, it is an emerging metric that has shown promise in various clinical diagnosis and evaluation of eye diseases and surgeries. We introduce the different methodologies used to measure CD.
