| description | Purpose: to carry out a comparative analysis of refractive outcomes and features during preoperational calculation of the biplanar intraocular lens (IOL) with iridocapsular and iridovitreal fixation.Patients and methods. Study included the analysis IOL model RSP-3 implantation after phacoemulsification cataract surgery with subluxated lens grade 2. Analyzed 309 eyes of 304 patients with iridocapsular (n = 44) (ICF) and iridovitreal fixation (n = 265) (IVF). In both groups IOL power was calculated with use of A- constant (118.2) recommended by manufacturer. Mean period of examination was 6 months. To count optimized A-constant in both groups we used next data: IOL power and axial length before surgery, keratometry, spherical equivalent and IOL effective position during 6 months after surgery.Results. In group with ICF postoperative refraction was achieved ± 0,5 D in 10 cases (23%), in group IVF — in 29 cases (11%). Mean value of optimized A-constant for IOL model RSP-3 in groups with ICF and IVF were 117.2 ± 1.18 (114.0–120.8) and 116.9 ± 1,89 (109.6 до 123.6). There were no statistically significant difference between compared groups (p = 0.46).Conclusion. Use of A-constant recommended by manufacturer do not allow achieving target refraction in most cases. Mean values of biplanar IOL A-constant counted for ICF and IVF were 117,2 and 116,9 respectively, what should be taken into account during IOL power count, according to its fixation method. |
