Purpose: To evaluate the outcome of eyes with large Descemet's membrane (DM) perforation during deep anterior lamellar keratoplasty (DALK).

Methods: A retrospective, interventional case series of 12 eyes with completed DALK, despite DM perforation larger than 4 mm in its widest dimension. The main outcome measures included graft clarity, endothelial cell density (ECD), corrected distance visual acuity (CDVA), and DM detachment.

Purpose: To describe the clinical presentation, risk factors, and treatment choices documented in a pediatric keratoconus population treated at a tertiary referral center in Alexandria, Egypt.

Methods: : A cross-sectional study of 80 patients with keratoconus aged 18 years or younger referred to the cornea clinic at the Alexandria University Main Hospital between July 2018 and October 2019 was included. Patients' history, initial presentation, best spectacle corrected visual acuity (BSCVA), clinical signs, topographic data, and treatment were recorded.

Purpose: To study the dynamics of big bubble (BB) formation in eyes with advanced keratoconus (KC) during deep anterior lamellar keratoplasty (DALK).

Methods: A retrospective review of medical records and videos of DALK surgeries performed during the period from January 2013 to December 2019 on keratoconic eyes. Eyes with formed BB, in the presence of a relatively clear stroma, were included.

Purpose: To describe a surgical technique to achieve the desired plane during deep anterior lamellar keratoplasty (DALK) in eyes with Descemet membrane (DM) tears due to previous hydrops.

Methods: This was a prospective, consecutive, interventional case series of DALK in 12 keratoconic eyes with healed hydrops. Dissection of the peripheral cornea was performed by air injection and using the microbubble incision technique as a guide to the clear predescemetic stroma.

Purpose: To review the outcome of 3 techniques for managing type 2 bubbles (between Descemet's membrane [DM] and stroma) formed during big bubble (BB) deep anterior lamellar keratoplasty (DALK) in different corneal pathologies.

Methods: This is an interventional case series study of patients with type 2 bubbles formed during BB DALK. Three techniques to complete DALK are described: the first is a DM baring technique similar to Anwar's BB technique, the second is the microbubble incision technique to preserve the pre-Descemetic support to DM, and the third is done in eyes with combined type 1 and type 2 BB (mixed bubble), where the type 1 bubble is opened and surgery is completed avoiding the type 2 bubble.

Article Synopsis
  • * A total of 20 patients were reviewed, with most undergoing penetrating keratoplasty (PKP), and complications included anterior segment injuries like iris prolapse and lens extrusion, as well as posterior segment issues like vitreous hemorrhage and retinal detachment.
  • * The final visual outcomes were generally poor, with only 25% achieving a best-corrected visual acuity (BSCVA) of 0.1 or better, while deep anterior lamellar keratoplasty (DALK) cases showed better outcomes compared to penetrating keratoplasty (PKP).
