“…The literature contained no information on the Lentis LT lenses for any comparison to be made. With respect to the AcrySof toric multifocal lens, our results contrast with those of other studies 14 that report a lens rotation of no more than 10°; in the current study, 17.68% of patients showed a rotation of at least this amount.…”

PURPOSE: To evaluate rotational stability and its influence on postoperative visual acuity of different monofocal and multifocal toric intraocular lenses (IOLs). METHODS:A prospective interventional study was designed. Ninety-one patients with a mean age of 71.65 ± 11.82 years were implanted with toric IOLs after phacoemulsification. Three monofocal toric IOLs (the Lentis LT [Oculentis, Berlin, Germany], enVista [Bausch & Lomb, Rochester, NY], and AcrySof IQ [Alcon Laboratories, Inc., Fort Worth, TX]) and one multifocal toric IOL (AcrySof IQ ReSTOR; Alcon Laboratories, Inc.) were implanted. Preoperative and postoperative images were taken to calculate the misalignment due to the marking method. To evaluate rotation in the different follow-up visits, another photograph was taken 1 hour and 1, 7 and 30 days postoperatively. Refraction, uncorrected distance visual acuity (UDVA), and corrected distance visual acuity were measured 30 days postoperatively. RESULTS:Postoperative UDVA was 0.1 logMAR or better in 64.6% of eyes implanted with monofocal IOLs and 46.4% of eyes implanted with multifocal IOLs. The enVista toric IOL showed the best UDVA compared to the other monofocal IOLs, with 81% of eyes with 0.1 logMAR or better. The mean misalignment in the total group studied was 0.07° ± 0.60°; 69.6% of monofocal IOLs and 67.9% of multifocal IOLs showed less than 5° of rotation. A correlation was found between postoperative UDVA and rotation in the monofocal and multifocal IOLs implanted (r = 0.439 [P < .011] and = 0.787 [P = .001], respectively).CONCLUSIONS: At 1 month postoperatively, UDVA was slightly more affected by IOL rotation in multifocal than monofocal toric IOLs. The marking method was also effective.[J Refract Surg. 2015;31(2):XX-XX.]

“…Recent studies (15)(16)(17) have shown the importance of considering the posterior corneal surface when determining total corneal astigma tism and planning astigmatism correction. The posterior cornea acts as a minus lens.…”

“…Furthermore, when choosing the IOL toricity, it is desirable to leave patients with slight with-the-rule astigmatism, due to the normal tendency for astigmatism to drift against-the-rule with advancing age. Thus, leaving this slight with-the-rule astigmatism prolongs the period of time in which the patient's corneal astigmatism is compensated by the toric IOL (15,23,33,48) .…”

“…Toric IOLs correct corneal astigmatism at the time of cataract surgery and are a predictable treatment in general (3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18) . Monofocal toric IOLs can be used to correct the patient's vision for distance, for near or for both (this latter being attained via monovision) (3)(4)(5)(6)(7)(8)(9)(10) , while multifocal toric IOLs aim at providing good uncorrected vision for near, intermediate and far (14)(15)(16)19) . Moreover, toric phakic IOLs are a largely reversible treatment option for pre-cataractous patients who are not good candidates for corneal refractive surgery and have clinically significant astigmatism (20)(21)(22) .…”
