Uncorrected and spectacle-corrected near visual acuity was easured using a Rosenbaum-Jaeger reading chart at 35 cm, and intermediate visual acuity at 60 cm. Uncorrected and spectacle- corrected distance visual acuity was measured using a Snellen chart fro 6 m.Visual acuity values were converted in logarithmic scale for statistical analysis.Worth, TX) five times daily for 1 week and four times daily for the following week.Six months postoperatively, we measured uncorrected and spectacle-corrected distance, intermediate and near visual acuity.A Scheimpflug imaging system (Pentacam; Oculus Optikgeräte Gmb H, Wetzlar, Germany) was used to evaluate IOL tilt and decentration according to de Castro et al (10) as follows: IOL decentration is obtained from the distance between the IOL center and pupillary axis.Positive horizontal coordinates stand for nasal in the right eye and temporal in the left eye.In the case of the AC group, the diameter of the CCC had to be 5.5 mm (7) to prevent the anterior capsule covering the optics of the AC intraocular lens.In the case of the MF group, a smaller, 4.75 mm (6) CCC was created to achieve an overlap over the IOL optic, as a large or eccentric capsulorhexis increases the risk of postoperative IOL misalignment (8,9). Patients were instructed to instill one drop of dexamethasone 0.1%-tobramycin 0.3% (Tobradex, Alcon Laboratories Inc, Ft.
The purpose of our prospective study was the comparison of the postoperative visual performance with a progressive-optic refractive and diffractive multifocal IOL and an accommodating IOL.
The accommodating IOLs try to imitate the function of the crystalline lens.
They are designed to transmit ciliary muscle contraction into a change of dioptric power of the lens.
A positive tilt around the y-axis stands for temporal tilt (nasal edge of the IOL moves forward) in left eyes.
By eliminating positive and negative signs, the magnitude of horizontal and vertical tilt could be determined without reference to any orientation. K.) obtained the tilt and decentration measurements (11, 12).
Since the distribution of parameters defined during postoperative examinations do not match the normal distribution according to the Shapiro-Wilks test, the comparison of the two study groups was performed using Mann Whitney U-test.
