Interface fluid syndrome (IFS) is a complication associated with laser in situ keratomileusis (LASIK) surgery where a fluid pocket in the corneal stroma decreases visual acuity. A systematic review of IFS cases using PRISMA guidelines was performed yielding a total of 33 patients. 2 outcomes were selected for logistic regression analysis: final corrected distance visual acuity (CDVA) and need for surgical management. Results showed 33.3% of patients required surgery, 51.5% had their IFS resolve within 1 month or sooner, and 51.5% had final CDVA 20/25 or better. Higher presenting intraocular pressure (IOP) and duration of IFS ≤1 month was associated with higher odds of final CDVA 20/25 or better (adjusted odds ratio [aOR] 1.12, P = .04; aOR 7.71, P = .02, respectively). Endothelial cell dysfunction led to 17.55 greater odds for requiring surgical compared to medical management (aOR 0.36, P = .04). Presenting IOP and duration of IFS predicted final CDVA, while prior endothelial cell dysfunction predicted need for surgery.

Unlabelled: Cell division is a fundamental process ensuring the perpetuation of all cellular life forms. Archaea of the order Sulfolobales divide using a simpler version of the eukaryotic endosomal sorting complexes required for transport (ESCRT) machinery, composed of three ESCRT-III homologs (ESCRT-III, -III-1, and -III-2), AAA+ ATPase Vps4 and an archaea-specific component CdvA. Here, we clarify how these components act sequentially to drive the division of the hyperthermophilic archaeon .

Background: Keratoconus in children is often more severe and rapidly progressive compared to adults. While Scheimpflug imaging (Pentacam) improves screening, there are no established pediatric guidelines. Due to challenges in diagnosis, we aimed to correlate clinical factors with abnormal imaging results to aid in the development of screening protocols.

Article Synopsis
  • The study analyzed 138 patients with contact lens-related bacterial keratitis (CLBK) over a 7-year period to understand their demographics, CL wear behavior, and treatment outcomes.
  • The majority of cases were linked to soft contact lenses, with Pseudomonas aeruginosa and Staphylococcus spp. being the most common bacteria found; poor hygiene was a significant factor in over half the cases.
  • Most patients responded well to topical antibiotics, achieving good visual acuity, although older age, female gender, and larger infection size were associated with poorer healing outcomes.

Article Synopsis
  • A study was conducted to evaluate the Eyecryl toric phakic IOL (pIOL) for patients with moderate-to-high myopic astigmatism, focusing on visual and refractive outcomes over three years.
  • The research included 52 eyes from 28 patients, showing a significant improvement in visual acuity and reduction in astigmatism, with 70% of eyes achieving better vision versus preoperative levels.
  • The findings indicate that the Eyecryl toric pIOL is effective and safe, though some patients experienced minor complications, such as cell loss and opacification issues.
