[Influence of endothelial graft thickness on postoperative visual acuity].

Aim: to assess the influence of the endothelial graft thickness on postoperative visual acuity following modified endothelial keratoplasty (UTDSAEK).

Material And Methods: The study included 49 patients with pseudophakic bullous keratopathy and no concomitant disorders of either the retina or optic nerve. Ultrathin Descemet's stripping automated endothelial keratoplasty (UTDSAEK) was performed in all cases.

[Photoacoustic monitoring of chorioretinal complex during laser coagulation of ocular fundus].

The effect of laser treatment on ocular fundus tissues depends on quite a number of factors, mostly uncontrollable, hence, laser output parameters may vary dramatically even within the same fundus. In classical procedure ('threshold' laser coagulation), these parameters are adjusted to ophthalmoscopically visible tissue color changes at the site of coagulation. However, this method does not work with modern subthreshold techniques, that are more tissue-saving and thus, produce no immediate and visible changes in the retina.

[Analyzing causes for opacification of acrylic IOLs].

Aim: to study the nature of intraocular lens (IOL) opacification depending on the patient's ocular status and general condition.

Material And Methods: A total of 9 patients (9 eyes) with 3-6 year history of progressive IOL opacification were enrolled. All the IOLs were acrylic (either hydrophilic--7 cases, or hydrophobic--2 cases).

[Evaluation of corneal biomechanics before and after up-to-date keratoplasty in patients with bullous keratopathy].

Unlabelled: Aim - to study biomechanical properties of the cornea in patients with bullous keratopathy before and after keratoplasty.

Material And Methods: Ocular response analyzer (ORA, Reichert) indices were studied in 37 patients (37 eyes) with bullous keratopathy before and after surgery - in 1, 2, and 6 months and then in 1, 2, 3, and 5 years. The following keratoplasty modifications were performed: ultrathin Descemet's stripping automated endothelial keratoplasty (UTDSAEK) - in 17 cases, microkeratome-assisted posterior keratoplasty (MAPK) - in 13 cases, half top-hat penetrating keratoplasty (HTH PK) - in 7 cases.
