Unilateral Multifocal Intraocular Lens Implantation in a Patient with Adie’s Pupil
摘要： Purpose: To report a case of a patient with unilateral Adie’s pupil who underwent bilateral cataract extraction with multifocal and monofocal posterior chamber intraocular lens (IOL) implantation. Methods: A 74-year-old woman presented to our institution complaining of worsening near vision. Gross examination revealed a 6-mm fixed pupil on the right eye (OD) and a 5-mm pupil reacting to 3 mm with light on the left eye (OS). Slit lamp examination revealed a tonic pupil with an exaggerated pupillary constriction to dilute pilocarpine OD. Dilated exam revealed 2–3+ nuclear and cortical lens changes bilaterally. The patient’s active lifestyle, personality, and biometry measurements made her a good candidate for multifocal IOL (MfIOL) implantation OS. Femtosecond laser-assisted cataract extraction with a ReSTOR +3 ADD (SN60D1) implantation was performed OS. Monofocal lens implantation (SN60WF) was performed OD 6 months later. Results: One year postoperatively, our patient had an uncorrected visual acuity (VAsc) of 20/15 for distance and J10 for near OD. Her VAsc was 20/25 +1 for distance and J1 for near OS. Visual acuity when using both eyes was 20/15 for distance and J1 for near. Conclusion: Optimizing success for MfIOL implantation is a multifactorial process. Large pupils preoperatively are of particular concern, as this may lead to increased dysphotopsia with pupil-dependent MfIOLs. Thus, patients with unilateral mydriasis, such as Aide’s pupil, may have a beneficial outcome combining multifocal-monofocal implantation after bilateral cataract extraction, especially if they are not a candidate for monovision but desire spectacle independence.

Clinical Evaluation of Functional Vision of +1.5 Diopters near Addition, Aspheric, Rotational Asymmetric Multifocal Intraocular Lens
摘要： To evaluate postoperative outcomes and visual performance in intermediate distance after implantation of a +1.5 diopters (D) addition, aspheric, rotational asymmetric multifocal intraocular lens (MIOL). Patients underwent bilateral cataract surgery with implantation of an aspheric, asymmetric MIOL with +1.5 D near addition. A complete ophthalmological examination was performed preoperatively and 3 months postoperatively. The main outcome measures were monocular and binocular uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), uncorrected intermediate visual acuity (UIVA), distance corrected intermediate visual acuity (DCIVA), uncorrected near visual acuity (UNVA) and distance corrected keratometry, and manifest refraction. The Salzburg Reading Desk was used to analyze unilateral and bilateral functional vision with uncorrected and corrected reading acuity, reading distance, reading speed, and the smallest log-scaled print size that could be read effectively at near and intermediate distances. The study comprised 60 eyes of 30 patients (mean age, 68.30 ± 9.26 years; range, 34 to 80 years). There was significant improvement in UDVA and CDVA. Mean UIVA was 0.01 ± 0.09 logarithm of the minimum angle of resolution (logMAR) and mean DCIVA was -0.02 ± 0.11 logMAR. In Salzburg Reading Desk analysis for UIVA, the mean subjective intermediate distance was 67.58 ± 8.59 cm with mean UIVA of -0.02 ± 0.09 logMAR and mean word count of 96.38 ± 28.32 words/min. The new aspheric, asymmetric, +1.5 D near addition MIOL offers good results for distance visual function in combination with good performance for intermediate distances and functional results for near distance.

Clinical Results and Optical Quality of Diffractive Multifocal Intraocular Lens
摘要： Purpose: To compare postoperative clinical outcomes, optical quality, and patient satisfaction between two types of diffractive multifocal intraocular lens (IOL, Acri Lisa 366D and Acrysof ReSTOR +3.00 D). Methods: In a total of 68 eyes, one of two diffractive multifocal IOL (Acri Lisa 366D and Acrysof ReSTOR +3.00 D) was implanted after cataract extraction. Visual acuity was measured postoperatively at one week, 1 month, and 6 months. Contrast sensitivity, wavefront aberration, and visual function were determined via questionnaire at postoperative 1 month. Results: Intermediate visual acuity of Acri Lisa 366D and Acrysof ReSTOR at 6 months were 0.31 ± 0.14, and 0.24 ± 0.11 (log MAR), respectively. At 6 months, near and distant visual acuity results showed no significant differences between the two groups. The photopic contrast sensitivity of Acri Lisa 366D at 6 cycles/degree was 55.36 ± 7.40 and showed significant differences with Acrysof ReSTOR (47.25 ± 9.67). The mesopic contrast sensitivity values of Acri Lisa 366D and Acrysof ReSTOR were 40.26 ± 11.38 and 28.97 ± 10.45, respectively, and the spherical aberration values were 0.037 ± 0.039 μm and 0.105 ± 0.066 μm. The spherical aberration of Acri Lisa 366D was significantly lower than that of Acrysof ReSTOR. Total and high order aberration, coma, and trefoil show no significant differences between the two groups. Conclusions: The Acri Lisa 366D multifocal IOL showed better contrast sensitivity and spherical aberration compared to Acrysof ReSTOR multifocal IOL, which had an effective intermediate visual acuity.

Comparison of the Visual Outcomes after Cataract Surgery with Implantation of a Bifocal and Trifocal Diffractive Intraocular Lens
摘要： Purpose: To evaluate and compare visual outcomes and optical quality after implantation of a bifocal (Acrysof ReSTOR? SN6AD1) or trifocal (AT LISA? tri 839MP) diffractive intraocular lens (IOL). Methods: Fifty-one eyes of 43 patients undergoing cataract surgery were enrolled and assigned to one of two groups: the trifocal group, comprising 24 eyes implanted with the trifocal diffractive IOL (AT LISA? tri 839MP), and the bifocal group, comprising 27 eyes implanted with the bifocal diffractive IOL (Acrysof ReSTOR? SN6AD1). Visual acuity (distant, intermediate, and near vision) and refractive postoperative outcomes were evaluated at one and three months postoperatively. Measurements of optical quality (using OQAS II?), contrast sensitivity (using CGT-2000?), automated visual field examination, and evaluation of defocus curve were performed three months postoperatively. Results: No statistically significant differences between the two groups were found in three-month postoperative distant and near (40 cm) visual acuities and optical quality. However, intermediate (63 cm, 80 cm, and 100 cm) visual acuities were significantly better in the trifocal group. Distant contrast sensitivity (5 m) under mesopic conditions was significantly better with the bifocal lens, whereas near contrast sensitivity (30 cm) under mesopic and scotopic conditions was significantly better with trifocal lens. There was no statistical difference between the groups under photopic conditions. In the defocus curve, the visual acuity was significantly better at intermediate distance in the trifocal group. Conclusions: Trifocal diffractive IOLs provide significantly better intermediate vision than bifocal IOLs, with equivalent postoperative levels of distant and near vision and ocular optical quality. Further, they provide better near contrast sensitivity under scotopic condition compared to diffractive bifocal IOLs.
