Summary:
In the retrospective study the authors evaluate clinical results of phototherapeutic
keratectomy (PTK) that is one of the alternative methods used in treatment
of some of the supercifial corneal diseases. The authors present the group of 89
eyes of 63 patients with diagnose: dry spot corneae in 69 eyes (77.5 %), recurrent
corneal erosion in 13 eyes (14.5 %), corneal dystrophy in 2 eyes (1.8 %), recurrent
herpes simplex keratitis in 3 eyes (2.7 %), recurrent pterygium in 2 eyes (1.8 %),
atopic keratoconjunctivitis with mucous plaque in 1 eye (0.9 %). The average age
was 45.2 years (14-84 years) and average follow-up period was 29 months (3-52
months). The operation was done with the use of device Keracor 117 (ArF excimer
laser) in topical anaesthesia, with the average zone of ablation 4.1mmandaverage
depth of ablation 24 in one go. In ten cases was the operation carried out
repeatedly.
We evaluated the postoperative complications, postoperative changes of refraction
and final the best corrected visual acuity. For low percentage of postoperative
complications, decrease or disappearance of subjective difficulties and improvement
of visual acuity with minimal stress for the patient we can recommend PTK
as save and efficient method in treatment of corneal diseases mentioned above.
