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.
对80名6至14岁、远视度数在3.5至9.5屈光度之间且散光度数在0.75至2.75屈光度之间的儿童,应用于远视矫正的手术技术,即板层角膜切开术(LK)、热角膜凝固板层角膜切开术(LKTKC)和瓣下光角膜切除术(LASIK)的结果进行了分析。随访时间为1至3年。LASIK(散光减少1.61±0.43屈光度或78%)被证明是矫正散光性远视性屈光参差的最佳方法。LASIK(屈光参差减少3.44±0.44屈光度或80%)在矫正高达3.0屈光度(含)的球面远视性屈光参差时更可取;LK方法(临床验光改善4.37±0.87屈光度)对3.0至5.5屈光度的屈光参差有效;LKTKC对5.5至7.5屈光度的屈光参差有效。与LK相比,后者可确保角膜屈光改善超过2屈光度(2.15±0.44屈光度)。TKC可作为在较长时间段内进行的单阶段手术。LASIK在散光超过1.5屈光度时更可取。
