Abstract
AIM: To evaluate the results of the effectiveness of cryogenic scleroplasty.
MATERIALS AND METHODS: 184 children (313 eyes) (mean age 11,72 ± 3,76 years) with moderate and high progressive myopia were examined before and after cryogenic scleroplasty (main group) and Pivovarov’s scleroplasty (control group).
RESULTS: A smaller average annual difference in the spherical equivalent of refraction (∆SEav) and the average annual gradient of the axial length (∆ALav) were recorded in the group of patients after cryogenic scleroplasty according to the data obtained during the two-year follow-up. ∆SEav was –0,48 ± 0,45 diopters in the main group and –0,51 ± 0,34 diopters in the control group in children of the younger age subgroup (up to 9 years old); –0,35 ± 0,31 diopters in the main group and –0,69 ± 0,61 diopters in the control group (p = 0,047) in the older age subgroup (9 years and older). ∆ALav in the main group was 0,15 ± 0,11 mm in children under 9 years of age, 0,31 ± 0,14 mm (p = 0,016) in the control group; 0,29 ± 0,18 mm and 0,34 ± 0,32 mm in children 9 years old and older, respectively.
CONCLUSIONS: The proposed technology of cryogenic scleroplasty has two surgical approaches in the lower-internal and upper-external parts of the eyeball; the scleroplastic material adheres evenly to the sclera, covers all four quadrants of the eyeball; it is fixed under the rectus muscles of the eye; at a 24-months follow-up period showed a good stabilizing effect.
