40 YAŞDAN YUXARI PASİYENTLƏRDƏ KERATOREFRAKTİV ƏMƏLİYYATLARIN XÜSUSİYYƏTLƏRİ (BUYNUZ QİŞA ABLYASİYASININ İNCƏLİKLƏRİ)

Abstract

SUMMARY

Aim - features of corneral ablation in patients with myopia older than 40 years.

Material and methods
The investigation included 20 patients (40 eyes) at the age of 40-50 years of old. The patients were divided into
two groups: I group - patients aged 40-45 years, the operation plan was carried out in accordance with emmetropia
in both eyes; the II group - patients aged 45-50 years in which the dominant eye was with emmetropia, and the
second eye - sph -1 D (control eye).
The surgeries were carried out on the Wafelight EX 500 devices (Alcon, USA) and Wafelight FS 200 (Alcon,
USA) by Wavefront Optimazed method.

Results
The patients were under the observations during 1-6 months. All patients gave the high visual acuity
postoperatively. In patients of the I group the refraction indices has changed in accordance with emmetropia and
they were completely rid themsebves of wearing glasses in the distance. In accordance with the age they were
prescribed the glasses to the near. In the II group of patients in one eye there were changes in accordance with
emmetropia, in the second control eye the refractive indices were within -1±-0,5 D. Thanks to this the problem of
wearing glasses near and far was solved.

Conclusion
So, in patients older than 40 years who had excimer laser surgery, the lifestyle has changed in the positive
direction.
