Abstract Details

Purpose:

To study the possibility of the correction of low hyperopic refraction error by means “back-up” angulated elastic IOL rotation in short-term period after cataract surgery, determine the refractive effect of rotation, depending on the optical power of the implanted IOL (Alcon Acrysof SN60AT; IQ SN60WF) and the axial lengths of the eye.

Setting:

The S.N. Fyodorov Eye Microsurgery Federal State Institution (Moscow), Russia

Methods:

The hyperopic mistake of IOL power calculation was determined in 12 cases up to 5th day after standard micro incision cataract surgery. The main reasons were: Biometry error in eyes with high ametropia, hard cataract and after retinal detachment surgery. Keratometry error in eyes after corneal refractive surgery and after contact lens removal. IOL calculation error in eyes with vitreal blocks, natural lens subluxation, after using capsular tension ring during operation and due to unadequate A-constant. Examination included visometry, refkeratometry, pneumotonometry, anterior chamber OCT. The refractive effect of IOL transposition was calculated by the method (MICOF/ALF).

Results:

To correct the hyperopic refraction error we used the “back-up” rotation of the elastic IOLs (Alcon SN60AT; SN60WF) under topical anesthesia by means of bimanual IA system not longer than 1 week after phaco procedure. According to refractometry the mean values of optical changes 1.95 ± 0.77D depends on the initial refraction of the lens. OCT image confirmed the decrease of the cornea -IOL distance. Long-term observation results are more than 8 years.

Conclusions:

Procedure of IOL reverse in the capsular bag is safe, have no influence on hydrodynamic and iris pigment dispersion. The optical outcome depends on the initial IOL power and add to 1.25 up to 2.75D. The incidence of posterior capsule opasification is not statistically different. Patients are satisfied with the quality of vision.
