“…Nah-, mittel-und entfernungsabhängig am besten korrigierte Sehschärfe und unkorrigierte Sehschärfe wurden zu Beginn und 3 [1], considerable development has occurred in the field of intraocular lenses (IOLs) to correct a wider range of refractive errors and achieve better visual performance. Amongst the most researched properties are the capacities to achieve spectacle independence and optimal visual acuity regardless of focal lengths and light conditions, as well as the reduction of visual aberrations [2]. A wide range of designs and optical properties were developed in an attempt to achieve this, including refractive, diffractive, refractivediffractive, and apodized diffractive multifocal IOLs [3,4].…”

“…They are, however, known to produce a subnormal visual performance in the intermediate range, which, with the rise of computer use, can significantly impair a patientʼs quality of life [6,7]. Other common adverse outcomes of multifocal IOLs are visual aberrations and photic phenomena, including glares and halos, as well as a reduced contrast perception [2,8].…”

Purpose To assess the visual performance, clinical and quality of life outcomes, and subjective patient satisfaction after implantation of a new refractive/extended depth of focus (EDOF) hybrid intraocular lens (IOL). Methods This is a monocentric, retrospective study of 29 patients (45 eyes), carried out in a tertiary care glaucoma research centre. All patients underwent implantation of a Lucidis (Swiss Advanced Vision, SAV-IOL SA, Neuchâtel, Switzerland) IOL during cataract surgery. Near, intermediate, and distance best-corrected visual acuities and uncorrected visual acuities were collected at baseline and 3 months postoperatively. Adverse events, contrast sensitivity, optical aberrations, subjective satisfaction, and spectacle independence were also analysed at 3 months. Results At 3 months postoperatively, the mean photopic uncorrected monocular distance, and intermediate and near visual acuities were 0.2 logMAR (~ 20/32), 0.07 logMAR (~ 20/23), and 0.15 logMAR (~ 20/28), respectively. Mean best-corrected visual acuity was 0.05 logMAR (~ 20/23) for distance and 0.03 logMAR (~ 20/21) for near vision. Mean photopic contrast sensitivity was 1.5 log. The mean root mean square (RMS) was 0.119 ± 0.05 µm. Subjectively, over the 3-month follow-up, 9% of patients (n = 4) complained of halos, and 2% (n = 1) of photophobia. No other adverse events were noted. Conclusions The Lucidis IOL demonstrates a good safety profile, with an acceptably low complication rate. While the uncorrected visual performance of this new optical design is inferior to that of other EDOF IOLs for distance vision, it achieves better results in intermediate and near vision, with consistently near-normal contrast sensitivity. Interestingly, self-reported spectacle independence and subjective patient satisfaction were high for all distances.

“…Some recent studies reported that significantly higher values of OSI and lower values of MTF cutoff and SR were found in the multifocal phakic eyes than monofocal IOL eyes and normal elder [41,42]. The diffractive or refractive rings in theoptics of multifocal IOLs may be partially responsible for causing scatter, resulting in moderate glare [41]. Thus, assessing the decision of laser capsulotomy after multifocal IOL implantation may require more other parameters.…”

Background: To evaluate whether the Optical Quality Analysis System (OQAS) can serve as a valuable additional indicator for appropriate posterior capsulotomy referral. Methods: One hundred and five eyes from 96 patients undergoing capsulotomy were divided into precapsulotomy logMAR CDVA ≤ 0.1 group and logMAR CDVA > 0.1 group. CDVA， and the Visual Function 14 index (VF-14) score were estimated before and 1 month after capsulotomy. Objective scattering index (OSI) value was measured by using the OQAS. Posterior capsule opacification (PCO) severity was assessed with Evaluation of PCO 2000 (EPCO 2000) software. Results：In logMAR CDVA > 0.1 group, the correlations of OSI, logMAR CDVA, EPCO score and VF-14 score were very strong preoperatively. In logMAR CDVA ≤ 0.1 group, preoperatively, OSI was correlated with logMAR CDVA (r = 0.451), EPCO score (r = 0.789), and VF-14 score (r = 0.852). LogMAR CDVA has weak correlation with VF-14 score (r = -0.384) and EPCO score (r = 0.566). VF-14 score was correlated with EPCO score (r = -0.669). In the logMAR CDVA ≤ 0.1 group, there was no significant difference in logMAR CDVA between precapsulotomy and postcapsulotomy (P > 0.05). In the two groups, all the other optical quality parameters were significantly improved after capsulotomy (P < 0.05). Conclusions：The OSI was useful for the evaluation of PCO and prediction of beneficial capsulotomy. Especially for patients with slight PCO and better visual acuity, OSI is more valuable than CDVA and a complete objectivity examination. Trial registration: The study protocol was registered at the Chinese Clinical Trial Registry. Register: ChiCTR1800018842 (Registered Date: October 13th, 2018).

“…A large number of literatures [20,21,22] have reported that the decrease of retinal imaging quality after cataract phacoemulsi cation was closely related to the change of total ocular wavefront aberration. The changes of total aberrations of the whole eye after surgery were mainly related to the changes of wavefront aberrations of the anterior corneal surface and the changes of IOL wavefront aberrations of the replacement [23,24,25,26] .…”

Background We aimed to evaluate the long-term clinical outcomes of Toric intraocular lens (Toric IOL)and Acrysof IQ Restor Toric +3.0D intraocular lens (ART +3.0D IOL)in patients with cataract and corneal astigmatism.Methods Fifty-eight eyes (46 participants) that had Toric IOL implantation, forty-three eyes (31 participants) that had ART +3.0D IOL implantation, were included in the study. All participants were assessed preoperatively, 3, 6, 12 and 24 months postoperatively. Primary outcomes measure: uncorrected distance visual activity (UCDVA), uncorrected near visual acuity (UCNVA), astigmatism and IOL axis alignment, defocus curve, contrast sensitivity and ocular aberration.Results UCDVA was better than 0.3 LogMAR at 3, 6, 12 and 24 months after surgery in both groups, and UCDVA was significantly improved after surgery than before ( P <0.05). All patients with ART +3.0D IOL implanted after surgery achieved or exceeded the near-vision of Jr3, which could meet the needs for removal of lens. At 3, 6, 12 and 24 months after surgery, the residual astigmatic was (0.28±0.20) diopters(D), (0.32±0.25) D, (0.31±0.16) D, (0.32±0.22) D in Toric group, and (0.27±0.17) D, (0.31±0.21) D, (0.30±0.19) D, (0.33±0.20) D respectively in the ATR group. Compared with preoperative corneal astigmatism, the difference was statistically significant ( P <0.05). The IOL axial mobility of all the patients was less than 5°in the two groups within 2 years after the operation. There was no difference in aberrations between the ART group and the Toric group under 3mm pupil, and there was statistically significant difference between the ART group and the Toric group under 5mm pupil ( P <0.05).Conclusions Toric IOL and ART + 3.0D IOL implantation were safe and effective in the treatment of cataract with corneal astigmatism,and ART + 3.0D IOL provided adequate near vision. The effect had long-term stability.
