The results of surgical techniques applicable to
hypermetropia correction, i.e. lamellar keratotomy (LK), lamellar keratotomy with thermal keratocoagulation (LKTKC) and sub-flap
photokeratectomy (
LASIK), in 80 children, aged 6 to 14, with
hypermetropia ranging from 3.5 to 9.5 diopters and with
astigmatism ranging from 0.75 to 2.75 diopters are analyzed. The follow-up varied from 1 to 3 years.
LASIK (reduction of
astigmatism by 1.61 +/- 0.43 diopters or 78%) was proven to be an optimal method in the correction of astigmatic hypermetropic
anisometropia.
LASIK (reduction of
anisometropia by 3.44 +/- 0.44 diopters or 80%) is preferable in the correction of a spherical hypermetropic
anisometropia of up to 3.0 diopters inclusively; the LK method (an improvement of clinical refraction by 4.37 +/- 0.87 diopters) is effective in
anisometropia of 3.0 to 5.5 diopters; and LKTKC is effective in
anisometropia of 5.5 to 7.5 diopters. The latter ensures an improvement of the corneal refraction by more than 2 diopters (2.15 +/- 0.44 diopters) versus LK. TKC is possible as a single-stage procedure made in the remote time period.
LASIK is more preferable in
astigmatism of more than 1.5 diopters.
