To compare the 12-month postoperative quality of vision and visual performance of 2 different refractive rotationally asymmetric multifocal intraocular lenses (IOLs). Cathedral Eye Clinic, Belfast, Northern Ireland, United Kingdom. Retrospective case series. Refractive lens exchange (RLE) patients were divided into 2 groups. Group A comprised eyes receiving a Lentis Mplus LS-312 MF30 IOL and Group B, eyes receiving a Lenstec SBL-3 IOL. Refraction, uncorrected (UDVA) and corrected distance visual acuities, uncorrected intermediate (UIVA) and near (UNVA) visual acuities, distance-corrected intermediate and near (DCNVA) visual acuities, and quality of vision were evaluated preoperatively and up to 12 months postoperatively. Each group comprised 90 eyes. Both groups had a high level of quality of vision 12 months postoperatively with no significant difference between the 2 groups (P = .919). There was no significant between-group difference in mean monocular and binocular UDVA, monocular UIVA, or monocular UNVA. Group B had statistically significantly better mean monocular DCNVA (P = .049), binocular UNVA (P = .011), and binocular DCNVA (P = .035). Group B had a higher percentage of complete spectacle independence. Both refractive rotationally asymmetric multifocal IOLs provided an excellent level of quality of vision 12 months postoperatively. Both IOL models restored distance, intermediate, and near visual function; however the IOLs in Group B provided better near visual performance.

To determine the degree of tolerance toward different magnitudes of residual refractive astigmatism and corneal astigmatism and the angles of corneal astigmatism after implantation of an asymmetric multifocal intraocular lens (IOL). Cathedral Eye Clinic, Belfast, United Kingdom. Retrospective comparative case series. The study enrolled patients having refractive lens exchange and implantation of a Lentis Mplus LS-312 MF30 IOL. Uncorrected (UDVA) and corrected distance visual acuities, uncorrected near and intermediate visual acuities, and quality-of-vision questionnaires were evaluated. Groups were categorized based on the magnitude of refractive astigmatism and corneal residual astigmatism. Refractive astigmatism of less than 0.50 diopter (D) and more than 0.50 D and corneal astigmatism of 0.50 D or less, 0.51 to 0.75 D, 0.76 to 1.00 D, and more than 1.00 D were categorized. The study comprised 117 patients (234 eyes). There was a significant difference in UDVA (P = .003), refractive sphere (P = .001), and defocus equivalent (P ≤ .001) between the residual refractive astigmatism groups; however, there was no difference in quality of vision (P = .28). The same was found for corneal astigmatism with UDVA (P ≤ .001) and quality of vision (P = .16). The angle of corneal astigmatism in relation to IOL placement did not statistically affect postoperative outcomes. The IOL appeared to subjectively tolerate residual astigmatism well despite a statistically significant difference in UDVA with higher magnitudes of residual astigmatism. The angle of residual corneal astigmatism in relation to IOL placement did not have a significant effect on postoperative outcomes.

To assess the 3-month and 12-month postoperative visual performance and subjective patient satisfaction after refractive lens exchange (RLE) with implantation of a rotationally asymmetric multifocal intraocular lens (IOL). Cathedral Eye Clinic, Belfast, United Kingdom. Prospective case series. The refraction, uncorrected (UDVA) and corrected distance visual acuities, uncorrected intermediate (UIVA) and near (UNVA) visual acuities, distance-corrected intermediate and near visual acuities, and a quality of vision (QoV) questionnaire were evaluated 3 months and 12 months after implantation of an SBL-3 IOL. The study enrolled 100 eyes of 50 patients. The mean monocular UDVA was -0.02 logarithm of minimum angle of resolution (logMAR) ± 0.12 (SD) 3 months postoperatively and -0.01 ± 0.10 logMAR at 12 months (P = .393). The mean monocular UIVA was 0.39 ± 0.11 logMAR and 0.41 ± 0.12 logMAR, respectively (P = .06). The mean monocular UNVA was 0.12 ± 0.13 logMAR and 0.14 ± 0.12 logMAR, respectively (P = .077). The mean QoV score was 8.26 ± 1.16 at 3 months with a significant improvement at 12 months, at which time the mean QoV score was 8.84 ± 1.08 (P ≤ .001). This asymmetric multifocal IOL provided excellent unaided vision with no significant difference in near, intermediate, and distance vision 3 months and 12 months postoperatively. However, there was a significant improvement in subjective outcomes at the second postoperative assessment, during which patients reported a significantly better QoV score and less blurred vision.

To compare the postoperative quality of vision between different bilateral placements of near segments of rotationally asymmetric refractive multifocal intraocular lenses (IOLs) and to determine how this affects visual performance. Cathedral Eye Clinic, Belfast, Northern Ireland, United Kingdom. Retrospective comparative case series. The study enrolled consecutive patients having refractive lens exchange and implantation of rotationally asymmetric multifocal IOLs. Group 1 received bilateral SBL-3 IOLs and Group 2 received bilateral Lentis Mplus LS-312 MF30 IOLs, with the near segments placed inferonasally in each group. Group 3 received a Lentis Mplus LS-312 MF20 IOL in the dominant eye with the near segment positioned superotemporal and a Lenstec SBL-3 IOL positioned inferonasally in the fellow eye. Binocular uncorrected (UDVA) and corrected distance visual acuities, binocular uncorrected near (UNVA) and intermediate (UIVA) visual acuities, binocular distance-corrected near and intermediate visual acuities, and quality of vision were evaluated over 3 months postoperatively. The study enrolled 180 patients (360 eyes). There was no significant difference between the groups in binocular UDVA, UIVA, and UNVA; however, there was a significant difference between the groups in quality of vision (P ≤ .001). Group 3 had significantly better overall quality of vision. When implanting rotationally asymmetric multifocal IOLs, a combination of superotemporal placement of the near segment (+2.00 diopter [D] addition [add]) in the dominant eye with inferonasal placement of the near segment (+3.00 D add) in the fellow eye yielded consistent, high overall quality of vision and uncorrected visual acuity.

Background . Dry eye disease (DED) is a multifactorial and one of the most common problems treated in an ophthalmic outpatient clinic. Due to the variability in presentation, diagnosis of DED consists of a combination of subjective and objective clinical tests. The purpose of this study was to assess the effectiveness of a handheld smartphone‐based infrared thermal (IRT) camera for screening symptomatic evaporative DED. Methods . This observational sex‐matched control study assessed IRT images of 184 right eyes (46 normal and 138 DED) of 184 participants. Evaporative DED was assessed using noninvasive tear breakup time, fluorescein staining, and the Chinese version of the ocular surface disease index (C‐OSDI) questionnaire and categorized into their respective dry eye symptomology group (none, mild, moderate, or severe). The ocular surface temperature (OST) at 8 anatomical regions of interest (ROI) (nasal conjunctiva, nasal limbus, nasal cornea, central cornea, inferior cornea, temporal limbus, temporal cornea, and temporal conjunctiva) were measured and compared using a handheld smartphone‐based IRT camera. The effectiveness of these 8 ROIs OST in detecting varying severity of DED was evaluated in terms of correlations with severity of DED and their area under the curve (AUC). Results . OST at the 8 anatomical ROI was significantly higher in DED participants than in the non‐DED group ( p < 0.05) except for inferior cornea, temporal limbus, and temporal conjunctival regions (>0.05). Analyzing 8 anatomical ROIs revealed that the nasal limbus had the highest Pearson correlation with the severity of DED (0.64, p < 0.001). Additionally, the nasal limbus ROI achieved the highest AUC of 0.79 (CI: 0.73–0.85; p < 0.05), sensitivity, and specificity (0.96 and 0.91) when comparing its ability to discriminated DED vs. non‐DED eyes. Conclusions . Rather than a diagnostic tool, handheld smartphone‐based IRT images can be considered as a rapid, noninvasive, and hygienic screening tool in discriminating DED and non‐DED and potentially alleviating inconvenience experienced during conventional tests.
