[Intracorneal selective stromal transplantation].

Unlabelled: Deep anterior lamellar keratoplasty or penetrating keratoplasty are currently considered the optimal methods of surgical treatment of stromal dystrophies and corneal degeneration. Despite certain advantages and benefits of these methods, they also have significant limitations: involvement of superficial corneal layers in the surgery, need for suturing, development of post-keratoplasty astigmatism etc.

Purpose: This study aimed to test and describe the new method of closed sutureless keratoplasty (intracorneal selective stromal transplantation), which was indicated in isolated dystrophic and degenerative pathology of the stroma.

[Transplantation of the Bowman's layer in combined treatment of recurrent pterygium].

Unlabelled: Pterygium is among the most frequent indications for extraocular ophthalmic surgery. The main method of pterygium treatment - its excision - is often combined with transplantation, non-transplantation, medication and other methods. However, the frequency of pterygium recurrence can exceed 35%, and the cosmetic and refraction outcomes satisfy neither the patient, nor the surgeon.

[On the issue of separate designation of the pre-Descemet's layer in the structure of the cornea].

Selective exchange of pathologically altered retinal layers is currently considered the most practical approach in corneal transplantation. Deep anterior lamellar keratoplasty (DALK) and Descemet membrane endothelial keratoplasty (DMEK) are often performed as pathogenetically substantiated transplantation methods. The technique and the course of surgery, possible complications, and achieved outcomes, among other things, depend largely on the pre-Descemet's layer, which was described more than 10 years ago by several ophthalmologists in varying detail.

[Descemet membrane endothelial keratoplasty after implantation of glaucoma drainage devices].

Unlabelled: Secondary decompensation of corneal endothelium, including transplanted, is a frequent long-term complication of glaucoma drainage surgery. According to literature data, after implantation of a glaucoma drainage device into the anterior chamber, the speed of endothelial cells density (ECD) loss increases significantly.

Purpose: To study the possibility of performing modified Descemet membrane endothelial keratoplasty (DMEK) with maximum graft diameter, and to assess its short-term effectiveness in the treatment of bullous keratopathy (BK) in the presence of a glaucoma drainage device in the anterior chamber.

Three-quarter DMEK in eyes with glaucoma draining devices to avoid secondary graft failure.

Purpose: To present a case series of a modified three-quarter Descemet's membrane endothelial keratoplasty (3/4-DMEK) technique to treat pseudophakic bullous keratopathy in the presence of a glaucoma drainage device (GDD) tube in the anterior chamber by reducing the risk of donor endothelial damage due to absence of donor endothelial cells overlying the GGD tube area.

Methods: In this prospective case series, four eyes of three patients with stable glaucoma underwent 3/4-DMEK surgery for pseudophakic bullous keratopathy after GDD insertion. The patients were followed up to 24 ± 2.

Intrastromal Descemet Membrane Transplantation as a Potential Alternative to Bowman Layer Inlays in Eyes With Advanced Keratoconus.

Herein, we report the outcomes of intrastromal Descemet membrane (DM) transplantation in corneas with advanced keratoconus. Three eyes (three patients) showed advanced keratoconus. No eye underwent prior UV-cross-linking or any other ocular surgery.

Five Keratoplasties From One Donor Cornea.

Purpose: To describe the feasibility of same-day, consecutive use of a single donor cornea in 5 patients with corneal pathology, who required anterior lamellar and endothelial keratoplasties.

Methods: Descemet membrane (DM) with endothelium was completely stripped from a single corneoscleral button and punched out from the endothelial side with a circular, standard punch. Using a custom-made punch for linear cutting of DM, we obtained 4 quarter-grafts (Q-graft).

A case of severe corneal flattening after Descemet stripping endothelial keratoplasty.

Purpose: To report a case of extreme corneal flattening after initially uneventful Descemet stripping endothelial keratoplasty (DSEK).

Methods: A 76-year-old man underwent uneventful DSEK for pseudophakic bullous keratopathy (PBK) in his left eye. Postoperative evaluations were performed using anterior segment optical coherence tomography and biomicroscopy.

Multicenter study of descemet membrane endothelial keratoplasty: first case series of 18 surgeons.

Importance: Surgeons starting to perform Descemet membrane endothelial keratoplasty (DMEK) should be informed about the learning curve and experience of others.

Objective: To document the clinical outcome of standardized "no-touch" DMEK and its complications during the learning curves of experienced surgeons.

Design, Setting, And Participants: Retrospective multicenter study.

Treatment of equinocavovarus deformity in adults with the use of a hinged distraction++ apparatus.

We evaluated the results following the use of the Volkov-Oganesyan-Povarov hinged distraction apparatus to correct equinocavovarus deformity of the foot in sixty-five adults (eighty-three feet). The deformity was secondary to ischemic and neuropathic changes after trauma to the foot and ankle, poliomyelitis, Charcot-Marie-Tooth disease, or untreated clubfoot. The deformity often was associated with severe neurotrophic changes, extensive scarring of the skin, callosities, or osteomyelitis of the foot, all of which usually preclude operative reconstruction.

Treatment of fractures in tubular bones by the Volkov-Oganesyan repositioning-compression apparatus.

The hinged compression external fixation device of Volkov and Oganesyan is widely used in Eastern Europe. The device facilitates repositioning, provides stable fixation, and permits early ambulation and weight-bearing.
