“…Likewise, our results in terms of predictability of refractive correction were also comparable to those reported for other modalities of toric IOLs [5][6][7][8] and in some cases even better. 9,10 Visser et al 9 found that residual refractive astigmatism of -1.00 D or less was achieved in approximately 90% of samples of eyes implanted with a toric multifocal IOL.…”

PURPOSE: To evaluate the visual, refractive, and aberrometric outcomes of a bitoric intraocular lens (IOL) and its stability and alignment within the capsular bag. METHODS:A retrospective study including 41 eyes of 24 patients with preexisting corneal astigmatism of 0.75 diopters or greater undergoing cataract surgery with implantation of the bitoric IOL AT TORBI 709M (Carl Zeiss Meditec, Jena, Germany). Visual and refractive outcomes were evaluated during a 3-month follow-up period. The misalignment between intended and real axis and the levels of corneal, internal, and ocular aberrations (KR-1W; Topcon, Tokyo, Japan) were also evaluated. RESULTS:A total of 76% and 97% of eyes had a postoperative spherical equivalent within ±0.50 and ±1.00 diopters of emmetropia, respectively. Likewise, a total of 86% and 95% of eyes had a postoperative absolute value of refractive cylinder of 0.50 or less and 1.00 or less diopters, respectively. Mean postoperative corrected distance visual acuity was 0.00 logMAR (20/20 Snellen). Mean values of postoperative monocular and binocular uncorrected distance visual acuity were 0.10 and 0.00 logMAR (20/25 and 20/20 Snellen), respectively. The aberrometric analysis confirmed that the magnitude of ocular higher-order aberrations was mainly due to corneal optics and that the corneal astigmatism correction was sufficient with the toric IOL. Mean absolute IOL misalignment was 3.5º with values ranging from 0º to 10º. CONCLUSIONS:The bitoric IOL AT TORBI 709M is able to provide a predictable correction of corneal astigmatism with low postoperative levels of ocular higher-order aberrations.[J Refract Surg. 2015;31(7): 431-436.] new concept of toric intraocular lens (IOL) has been recently developed and released, the bitoric IOL. This type of IOL distributes cylinder power symmetrically on the front and back surface of the IOL, and not only on one surface as with toric IOLs currently available.1 This optical design has the theoretical advantage of obtaining IOLs of better optical quality when high cylinders should be corrected.2 One example of this type of toric IOL is the AT TORBI 709M (Carl Zeiss Meditec, Jena, Germany), which uses bitoric, monofocal, and aspheric (aberration neutral) optics.1 Previous studies have shown excellent visual and refractive outcomes after cataract surgery with implantation of this specific model of IOL.

“…With the same type of toric IOL, Alió et al 18 obtained a mean value of IOL rotation of 3.35° ± 3.56°.

“…(20) Such vectorial astigmatism analysis is gaining popularity in literature in recent years, as an increasing number of articles employ it as analytical instrument. (1,4,7,8,21,22) Figure 4 compares mean magnitudes of pre and postoperative APV within each group and between groups. A statistically significant reduction in APV, considering preoperative and any postoperative APV, was found within each group (p value = 0.00).…”

“…If the eye scheduled for cataract surgery has a significant astigmatism, postoperative vision will be impaired by this refractive error, and patient will need spectacles to obtain adequate distance and near vision. For patients with significant astigmatism, solution was found with the invention of toric IOLs, which were designed for two functions: to restore visual acuity deteriorated by cataract and to correct corneal astigmatism [9][10][11][12][13]. Toric IOLs must be produced individually since each eye with the corneal astigmatism has a unique combination of spherical and astigmatic correction (regarding both the amount and the axis of astigmatism).…”

Introduction: The first generations of multifocal intraocular lenses (MFIOLs) were designed to provide patients good distance and near vision, but intermediate was not satisfactory. Trifocal, a bifocal of low-add and quadrifocal MFIOLs were invented, offering possibility to correct vision for distance, near, and intermediate tasks. The novel IOL, extended range of vision (EROV), is covering mostly intermediate and distance vision, with lower level of photic phenomena. Patients and methods: We have evaluated visual results in 4408 eyes implanted with different MFIOLs in 12 years period (2004-2016). Postoperative uncorrected visual acuity for far, intermediate, and near was evaluated. Postoperative satisfaction and complication rate and management of complications are presented. Results: In the first generation MFIOLs, almost 70% of eyes gained uncorrected distance visual acuity of 1.0. Uncorrected near visual acuity was J1-J2 in 95% of eyes with diffractive IOLs. Modern MFIOL designs enabled improvement of vision at intermediate distance, without compromising vision at far and near. Conclusion: With the first generations of MFIOLs, good distance and near uncorrected vision was achieved. With novel MFIOLs a very good uncorrected vision was achieved at far, intermediate and near, while with EROV lens, near vision was less satisfactory, but patients had less photic phenomena.
