Organization: S. Fedorov Eye Microsurgery Federal State Institution, the Volgograd Branch
Summary:

The purpose is to study the efect of FemtoLASIK operation on the state of accommodation, intraocular pressure and viscoelastic properties of the cornea in patients with myopic refraction. Material and Methods. Examined 84 patients (84 eyes) with myopia degrees before and after the operation Femtolasik. Results. In patients with mild myopia after Femtolasik, there was a decrease in the coefcient of accommodation microfuctuation (CAM) by 3.6 % and an increase in the coefcient of accommodation response (CAR) by 28.6 %, in patients with moderate myopia there was a decrease in the values of CAM to 11.1 % and an increase in CAR to 30 %, in patients with myopia of high degree of CAM increased by 14.4 %, and CAR 34 %, respectively. The decrease in the values of corneal-compensated intraocular pressure (IОPcc) was statistically signifcant. In the frst group decrease IОPcc amounted to 17.1 % in the second group 17.3 %, in the third of 25.8 %. Conclusion. An improvement in the state of accommodation is observed against the background of a decrease in the indicators of corneal- compensated intraocular pressure after performing the operation FemtoLASIK.

Summary:

Aim: analysis of clinical and functional results, histomorphological changes of corneas in the application of the method of corneal collagen crosslinking with the formation of a femtosecond intrastromal pocket. Material and Methods. We studied 20 patients (20 eyes) that were operated for progressive keratoconus (1-2 stage) with a peripheral zone of maximum ectasia arrangement via corneal collagen cross-linking with femtosecond formation of intrastromal pocket for introduction of a photosensitizerand local ultraviolet radiation. Results. The result was a decrease of surgery duration and reduction of the severity of pain in the early postoperative period. Conclusion. This method allows to increase the safety of the treatment of keratoconus, reducing the risk of postoperative complications.
