“…Weinand and colleagues used this technique immediately and 6 months after IOL implanation in 17 of 40 eyes implanted with the AcrySof SA60AT. 10 The other images could not be analysed due to insufficient dilation (IOL orientation required visibility of both haptic-optic junctions) and poor image quality. In addition, a different camera was used on each occasion and repeatability of analysis and image capture was not assessed.…”

“…[19] The most important factor is the position of multifocal-toric IOL during surgery and its rotation after surgery. [20] In the present study, we evaluated open-loop-haptic AcrySof IQ restore multifocal toric IOL (Alcon) and plate-haptic Acriva reviol multifocal toric IOL (VSY) lenses in terms of postoperative rotational stability, residual astigmatism and uncorrected distance and near visual acuity. We found that rotational degree of plate haptic IOL was higher in the postoperative 1st and 3rd months, although it is not statistically significant.…”

To compare the clinical outcomes of plate haptic and open-loop haptic toric multifocal intraocular lenses (IOLs). In this retrospective, comparative clinical trial, two different designs of multifocal toric IOL were implanted in 49 eyes of 38 cases with corneal astigmatism ≥ 0.75 Diopter (D). The cases that underwent AcrySof IQ restore multifocal toric IOL (Alcon, open-loop-haptic) implantation were assigned to Group1 (n=19) and the cases that underwent Acriva Reviol multifocal toric IOL (VSY, plate-haptic) implantation were assigned to Group 2 (n=30). After surgery, the groups were compared in terms of degree of IOL rotation, residual spherical refraction and astigmatism and uncorrected near and distance visual acuity. With regard to the results of postoperative 1st month, 3rd month, 6th month and 1st year, no difference was determined in terms of uncorrected distance visual acuity, spherical equivalent (SE), degree of astigmatism (CYL), degree of rotation, and uncorrected near visual acuity (p>0.05). Significant increase was determined in all postoperative follow-up periods in terms of the distance and near visual acuity as compared to preoperative values (p<0.05). There was no correlation between degree of rotation and age, axial length, SE and CYL (p>0.05). Clinical outcomes of plate haptic Acriva Reviol multifocal toric IOL and open-loop haptic Acrysof IQ multifocal toric IOL are similar. Both types of IOL effectively reduce astigmatism and provide satisfactory uncorrected distance and near visual acuities.

“…The technique with a pen and a pendulum marker at 0p and 180p was used and demonstrated to be imprecise, moreover, during the surgery it is not uncommon to lose the precise axis due to the ink washout by balance salt solution (BSS). Although, many techniques have been developed to determine the postoperative IOL rotational stability, new studies should be worried in precisely mark the axis prior surgery, such as the computer model based on preoperative slitlamp examination demonstrated by Robert Osher,MD on the American Society of Cataract Refractive Surgery meeting-San Francisco-2009 called "Fingerprinting technique" (7,8) .…”
