Maronda akaumbwa mumhando iyi yekuvhiya madiki, asingasviki 3mm, uye haadi suture, kuderedza njodzi yehutachiona hwemaronda uye corneal astigmatism. Haisi chete nguva yekushanda ipfupi, nguva yekudzorera zvakare ipfupi, varwere vanogona kudzorera maonero munguva pfupi mushure mekushanda.
3. Femtosecond laser yakabatsira kubvisa cataract
Iko kuchengetedzwa kwekuvhiya uye kurongeka kwelaser kurapwa kunovimbiswa.
4. Intraocular lens implantation
Lenzi rekugadzira rakagadzirwa nepamusoro polima rinoiswa muziso kuti ridzorere kuona.
