SUMMARY

Aim - to conduct a comparative analysis of the results of the Contoura Vision Topo-guidet Lasik (CVTL) and
the WavefrontOptimazed Lasik (WOL) used in excimer laser surgery

Material and methods
The studies were conducted on the basis of the excimer laser department of the National Center for Ophthalmology
named after acad. ZarifaAliyeva. The study material consisted of 10 patients (18 eyes), who underwent excimer laser
surgery CVTL — I group and WOL 16 patients (32 eyes) — II group. The age of patients ranged from 20 to 30 years.
All patients underwent visual acuity studies (with and without correction), biomicroscopy, refractometry, tonometry,
fundus research, and one of the main methods of the study was to assess the state of the cornea, which was conducted
using WaveLight® ALLEGRO Oculyzer ™ topography (ALCON, USA) and WaveLight® ALLEGRO Topolyzer ™
(ALCON, USA). These research methods were also carried out after the operation. Operations were performed using
the ALLEGRETTO WaveLight® EX500 devices (ALCON, USA) and WaveLight® FS200 (ALCON, USA).

Results
The results showed that more than 50% of patients who underwent excimer laser surgery using the CV
method, visual acuity after surgery increased by one line and more compared with indicators of visual acuity with
correction before surgery.In general, in 94% of cases in patients of group I visual acuity increased significantly
postoperatively. In patients of group II this figure was 84%, which indicates the advantage of the CV method. In
addition after the CV method, visual symptoms of patients such as photosensitivity, deterioration of night vision,
flickering vision were also reduced.
The results showed that immediately after treatment with the CV method in a month and in 12 months relatively
better visual acuity was obtained in patients undergoing surgery using the WavefrontOptimazed Lasik (WOL)
technique.

Conclusion
Thus, the Contoura Vision Topo-guidet Lasik (CVTL), the latest technology used in excimer laser surgery, is
one of the greatest achievements of refractive surgery, thanks to which the patients’ visual functionimproves.
