[Combined approach to cataract surgery in keratoconus].

Preparation for cataract surgery in patients with keratoconus (KC) is associated with particular challenges: calculating the optical power of the intraocular lens (IOL), selecting the appropriate IOL model, and considering additional interventions aimed at stabilizing KC and reducing irregular astigmatism. This article presents a fundamentally new approach to combined treatment of KC with cataract, consisting of two stages: first, performing bandage therapeutic-optical keratoplasty (BTOK), followed by cataract phacoemulsification as the second stage.

[Deep anterior lamellar keratoplasty in extrusion of an incomplete intrastromal corneal ring segment (clinical observation)].

Intrastromal corneal ring segments (ICRS) of in various shapes are used to correct structural changes in the cornea and improve visual acuity in keratoconus (KC). The most serious complications of the technology infection, vascular ingrowth, and extrusion. In this study a 44-year-old patient underwent deep anterior lamellar keratoplasty (DALK) 5 years after implantation of ICRS in the shape of an incomplete ring to treat its extrusion of up to 30%, vascular ingrowth into the cornea and corneal syndrome.

[Long-term outcomes of bandage therapeutic-optical keratoplasty in the treatment of keratoconus].

Unlabelled: Intrastromal keratoplasty has recently been widely used in the surgical treatment of keratoconus (KC). In 2013, a new type of interlamellar keratoplasty operation was developed - bandage therapeutic-optical keratoplasty (BTOK).

Purpose: Evaluation of the long-term outcomes of surgical treatment of stages II and III progressive KC with BTOK technique.

[On the tactics for surgical treatment of keratoconus in significantly altered corneal thickness].

Purpose: To evaluate the clinical and functional outcomes of bandage therapeutic-optical keratoplasty (BTOK) surgery in patients with keratoconus (KC) and significant changes in corneal thickness.

Material And Methods: Surgical treatment was performed in 15 patients (15 eyes) with stage IV KC aged from 22 to 51 years (mean age - 32.61±7.

[Comparative assessment of the quality of life of keratoconus patients before and after intrastromal keratoplasty].

Unlabelled: Surgical treatment of keratectasia, in addition to its cessation, is aimed at increasing the acuity and quality of vision. This can also significantly affect patient's quality of life. The criteria for assessing the quality of life does not always consider the balance between quantitative indicators and subjective perception, which can depend on the psychological aspect of self-esteem.

[Results of confocal microscopy of the cornea after bandage therapeutic-optical keratoplasty in keratoconus].

Unlabelled: Bandage therapeutic-optical keratoplasty (BTOK) is one of the modern methods of surgical treatment of keratoconus (KC) that allows to improve visual functions by changing keratotopographic and pachymetric parameters of the cornea in the zone of ectasia. Long-term results show that changes also affect the central part of the cornea, which tends to flatten.

Purpose: To compare the light confocal microscopy appearance of the cornea before and after BTOK surgery.

[Bandage lamellar-optical keratoplasty for post-excimer laser keratectasia].

Introduction: According to various sources, occurrence rate of keratectasia (KE) after Laser in situ Keratomileusis (LASIK) ranges from 0.04 to 0.2%.

[Modern methods of surgical treatment of keratectasias].

Keratectasia (KE) ranks as one of the main causes of impaired vision. The pathology is characterized by progressive thinning of the cornea, which causes its deformation, the appearance of irregular astigmatism, and the reduction of vision acuity. The article reviews modern surgical methods that can be used to prevent the progression and treat various types of KE.

[Bandage keratoplasty therapeutic-optical in treatment of progressing pellucid marginal corneal degeneration (a preliminary report)].

Purpose: To provide preliminary estimation of the effectiveness of bandage therapeutic-optical keratoplasty (BTOK; previously called inralamellar bandage keratoplasty) in patients with pellucid marginal corneal degeneration (PMD).

Material And Methods: The study included 7 patients (8 eyes) with PMD aged 35 to 55 years operated with intralamellar bandage keratoplasty, the follow-up period comprised 3, 6, and 12 months after the surgery.

Results: All patients with PMD operated with intralamellar bandage keratoplasty showed increase in visual acuity to an average of 0.

[Objective assessment of donor material for penetrating corneal transplantation].

Unlabelled: Reliable suitability evaluation of donor material is the crucial issue of penetrating corneal transplantation. The main parameter to be considered is endothelial cell density (ECD). However, when it comes to practice, one has to admit significant variation in ECD readings of cadaver corneas obtained by different methods.
