AI Article Synopsis
- The study aimed to assess the rate of postoperative ectasia in patients who underwent LASIK with femtosecond laser flap creation, specifically focusing on those without known preoperative risk factors.
- Out of 1,992 eyes reviewed, 5 cases of ectasia were identified post-surgery; 4 showed potential signs of forme fruste keratoconus (FFKC) during retrospective analysis, while 1 had no identifiable preoperative risks.
- The overall rate of ectasia after LASIK at the center was 0.25%, with a specific rate of 5.8% for eyes with unrecognized FFKC that went on to develop ectasia.
Article Abstract
Purpose: To report the rate of postoperative ectasia after laser-assisted in situ keratomileusis (LASIK) with femtosecond laser-assisted flap creation, in a population of patients with no identified preoperative risk factors.
Methods: A retrospective case review of 1,992 eyes (1,364 patients) treated between March 2007 and January 2009 was conducted, with a follow up of over 4 years. After identifying cases of ectasia, all the patient charts were examined retrospectively for preoperative findings suggestive of forme fruste keratoconus (FFKC).
Results: Five eyes of four patients with post-LASIK ectasia were identified. All eyes passed preoperative screening and received bilateral LASIK. One of the five patients developed ectasia in both eyes. Three patients retrospectively revealed preoperative topography suggestive of FFKC, while one patient had no identifiable preoperative risk factors. Upon review of all the charts, a total 69 eyes, including four of the five eyes with ectasia, were retrospectively found to have topographies suggestive of FFKC.
Conclusion: We identified four cases of post-LASIK ectasia that had risk factors for FFKC on reexamination of the chart and one case of post-LASIK ectasia with no identifiable preoperative risk factors. The most conservative screening recommendations would not have precluded this patient from LASIK. The rate of purely iatrogenic post-LASIK ectasia at our center was 0.05% (1/1,992), and the total rate of post-LASIK ectasia for our entire study was 0.25% (1/398). The rate of eyes with unrecognized preoperative FFKC that developed post-LASIK ectasia was 5.8% (1/17).

Article Synopsis
- This study aimed to create and validate a polygenic risk score (PRS) for keratoconus to improve how well we can identify people at higher risk for the condition, which can lead to serious vision problems after procedures like LASIK.
- Researchers used multi-trait analysis and data from large biobanks to build and assess the PRS models' accuracy in predicting keratoconus risk.
- The results showed that the new PRS models significantly improved the prediction of keratoconus risk, suggesting they could be useful in clinical settings to identify individuals at risk and potentially prevent complications after LASIK surgery.
Impact of Scleral Lenses on Visual Acuity and Ocular Aberrations in Corneal Ectasia: A Comprehensive Review.
J Pers Med

Ophthalmology, Campus Bio-Medico University, 00128 Rome, Italy.
Corneal ectasias, including keratoconus (KC), pellucid marginal degeneration (PMD), and post-LASIK ectasia, poses significant visual rehabilitation challenges due to the resultant irregular astigmatism, myopia, and higher-order aberrations (HOAs). These conditions often resist traditional corrective methods, necessitating advanced optical solutions. Scleral lenses (SLs) have emerged as a primary non-surgical option for managing these complex corneal irregularities.

Post-laser-assisted keratomileusis (LASIK) corneal ectasia is a severe complication of corneal refractive surgery, and cryopreserved lenticules from hyperopic small incision lenticule extraction (SMILE) may offer a promising treatment though their long-term safety and efficacy are still under investigation. In this prospective case series, six eyes from six patients with post-LASIK ectasia received lenticules (mean cryopreserved time: 63 days). The procedure involved lifting the corneal flap, implanting the lenticule, and repositioning the flap.

- Large language models like ChatGPT-3.5 have potential for aiding self-directed medical learning, but their accuracy in specialized topics is under scrutiny.
- A study with 23 medical students compared ChatGPT-3.5 to traditional internet searches regarding the Randleman criteria, revealing ChatGPT-3.5 was only accurate for 26.1% of responses, whereas internet searches were 100% accurate.
- The findings suggest that ChatGPT-3.5 can mislead users, and students should critically evaluate its outputs while future efforts focus on improving AI accuracy and prompt effectiveness.

Purpose: To evaluate the variation and stability of the posterior cornea surface parameters (posterior cornea curvature [PCC], posterior cornea astigmatism [PCA], and posterior cornea elevation [PCE]) after femtosecond laser-assisted in situ keratomileusis (LASIK) in patients with myopia and myopic astigmatism over a period of 6 months or longer.
Methods: This retrospective study comprised 284 right eyes. Patients aged 18 years or older with myopia up to -12.
