Summary:
The problems of mild and high hyperopia surgical correction are complicated
and an individual approach is needed.
The aim of the study was to evaluate long-term efficiency and safety of two
types of refractive procedures in mild and high hyperopia correction: LASIK
and ICL (phakic intraocular posterior chamber contact lens) implantation.
The authors evaluated a group of 37 eyes of 20 patients; the average age was
36.3 years ± 11.8 (SD) and the follow-up period was 28.1 months ± 10.2 (SD) after
LASIK procedure, and a group of 21 eyes of 13 patients; the average age
was 28.6 years ± 6.1 (SD) and the follow-up period 30.4 months ± 20.9 (SD) after
the ICL implantation. They compared occurrence of preoperative, intraoperative
and postoperative complications in both methods. They specified
the efficiency and safety of the procedure by means of so called efficiency
and safety index. With a questionnaire they evaluated the patient’s subjective
satisfaction with the refractive procedure. In the group of hyperopic
LASIK, they proved statistically significant appearance of the refractive error
regression, number of performed re-operations, appearance of the peroperative
decentration of the photoablation zone and induced astigmatism
(p < 0.05). In the ICL group, the repeated preoperative sessions for Nd-YAG
laser iridotomies were necessary. Postoperatively, the appearance of keratitis
striata, syndrome of the late pigment dispersion, and glare were statistically
significant (p < 0.05). The authors also demonstrated higher efficiency
and safety of the ICL implantation method comparing to LASIK during the
whole follow up period (p < 0.05), and also higher subjective satisfaction after
ICL implantation. Conclusion: Comparing the intraocular procedure
(ICL) to the laser method (LASIK), in mild and high hyperopia correction, the
higher efficiency and safety was achieved by ICL implantation.
