To describe the results of Descemetstripping automated endothelial keratoplasty (DSAEK) for congenital hereditary endothelial dystrophy (CHED). Methods: The medical records of all patients with CHED who underwent DSAEK at our institution were reviewed. A standard DSAEK was performed in all cases with the exception of the Descemet membrane not being removed in patients younger than 12 months. A thorough ophthalmic examination was performed preoperatively and at each postoperative visit in all patients. Results: Fifteen eyes of 8 patients with phakic eyes (4 male and 4 female) were included. The mean age was 9 years (range, 6 months to 30 years). The average follow-up was 15.9 months (range, 3 to 48 months). There were 4 cases of graft detachment, all of which were managed by rebubbling. All corneas were clear within 1 week after surgery.

Purpose: To report 5-year outcomes of ultrathin Descemet stripping automated endothelial keratoplasty (UT-DSAEK) with a central graft thickness intended to be <100 μm. Methods: This retrospective, consecutive, interventional case series included 354 eyes with endothelial decompensation due to various causes (Fuchs endothelial dystrophy, pseudophakic or aphakic bullous keratopathy, failed previous graft, herpetic endothelitis, or buphthalmos). Donor tissue was prepared using the microkeratome-assisted double-pass technique aiming at a graft thickness <100 μm. The Descemet membrane was stripped under air. The graft was delivered into the anterior chamber using the pull-through technique through a 3.2-mm clear corneal incision using a modified Busin glide. The best spectacle-corrected visual acuity (BSCVA), endothelial cell loss, graft survival rates, and immunologic rejection rates were evaluated. Results: Follow-up data at 1, 2, 3, and 5 years after UT-DSAEK were collected from 214, 172, 147, and 105 eyes, respectively. After excluding eyes with comorbidities, BSCVA better than or equal to  20/20 was recorded in 36.3%, 37.4%, 46.4%, and 53.4% of eyes, respectively, whereas BSCVA better than or equal to 20/40 was documented in 95.5%, 95.3%, 96.0%, and 96.6% of eyes, respectively. The mean endothelial cell loss was 35.4%, 42.3%, 43.3%, and 52.3%; Kaplan–Meier graft survival probability was 99.1%, 96.2%, 94.2%, and 94.2%, and Kaplan–Meier cumulative probability of a rejection episode was 3.4%, 4.3%, 5%, and 6.9% at 1, 2, 3, and 5 years, respectively. Conclusions: UT-DSAEK grafts allow excellent 5-year outcomes, including BSCVA, endothelial cell density, and survival rates comparable with those recorded post-Descemet membrane endothelial keratoplasty, but with a higher immunologic rejection rate.

Ophthalmologists should be aware of this easily reversible uveitis syndrome that is induced by a common glaucoma medication. Familiarity with this entity is essential in making the correct diagnosis and avoiding unnecessary investigations and interventions.

From the rise of modern corneal graft surgery in the late 1950s until recently, corneal transplantation for keratoconus almost exclusively consisted of a full-thickness transplant, termed penetrating keratoplasty. This technique involved the removal of all of the layers of the patient's central cornea and replacement with a full-thickness graft. Over approximately the past 20 years, a quiet revolution has occurred with the development of several other types of corneal transplantation surgery for keratoconus. In addition to full thickness grafts, several different types of partial thickness, lamellar grafts, have been developed and are viable alternatives to a full-thickness graft in selected patients. The main aim of these lamellar grafts is to selectively replace the corneal stroma, leaving intact the patient's own Desçemet's membrane and endothelial cells, the main target of allograft transplant rejection. In this article, we review the current options with regard to corneal transplantation for keratoconus and review the evidence comparing newer and more established techniques.

Corneal perforations associated with herpetic keratitis may not heal with glue application alone, and corneal transplantation surgery may be required to maintain the ocular structural integrity.
