Previous comparative studies show that triple Descemet membrane endothelial keratoplasty (DMEK) (i.e. phacoemulsification followed immediately by DMEK) has either equivalent or better visual outcomes than DMEK in pseudophakic patients.

The authors conducted a literature review about bilateral acute iris transillumination (BAIT) syndrome, a new and relatively unknown syndrome that should be described and made known to the greatest number to avoid potential diagnostic and therapeutic errors. The first cases date back only to 2004 and a total of 79 cases have been published to date, mainly in Europe and especially in Turkey and Belgium. It mainly affects young women between the ages of 30 and 50, and symptoms are often preceded by an upper airway infection.

Article Synopsis
  • The study aimed to investigate the relationship between corneal swelling (edema) and the loss of endothelial cells after cataract surgery using microcoaxial phacoemulsification in 85 patients.
  • Data was collected at various time points post-surgery, showing that significant corneal swelling was linked to greater endothelial cell loss, particularly noted 4 days after surgery.
  • Results suggest that measuring corneal thickness after surgery could serve as an indicator of potential endothelial damage, highlighting its importance in postoperative assessments.

Purpose: To evaluate and compare visibility and depth of the stromal demarcation line (DL) created after corneal collagen cross-linking (CXL) using anterior segment optical coherence tomography (AS-OCT) between 2 groups: CXL with isoosmolar and hypoosmolar riboflavin.

Methods: In this retrospective study performed at Metz-Thionville Regional Hospital, consecutive patients with progressive keratoconus underwent CXL using an accelerated protocol (10 min, 9 mW/cm ultraviolet-A). AS-OCT (RS-3000, Nidek) was performed at 1 month after surgery, with stromal DL visibility graded.

Purpose: We created a laboratory model of a cornea that was subjected to various pressures and thermal and mechanical factors to better understand the genesis of keratoconus deformation.

Methods: A steel base allowed for fixation of circular multilaminated patches of araldite (10 cm in diameter, 5 mm thick) in which the corneal anatomy was modeled. The model was plunged into a steam room (374°F/3 bars of pressure for 1 h) to ensure thermal homogeneity and was subjected to pressure using compressed air.

Objective: To assess objective and subjective visual outcomes achieved by patients with corneal endothelial dysfunction who have undergone surgical treatment with Descemet stripping automated endothelial keratoplasty (DSAEK).

Methods: A total of 40 eyes of 36 patients with corneal endothelial dysfunction underwent DSAEK. All were followed up for 1 year.

Purpose: To assess the impact of surgeon experience on early postoperative central corneal thickness (CCT) in eyes that have undergone phacoemulsification-based cataract surgery.

Methods: One hundred sixty eyes underwent phacoemulsification-based cataract surgery performed by an experienced surgeon (n = 110; senior group) or a surgically less experienced ophthalmic assistant (n = 50; junior group), using the divide-and-conquer or tilt-and-tumble technique for cataractous lens extraction. The primary endpoint was postoperative corneal edema 2 hours after surgery, determined by pachymetry-based CCT.
