The purpose of this study was to analyze ocular residual astigmatism (ORA) before and after implantation of two different optical types of non-toric multifocal intraocular lenses (MIOL) in pre-cataract patients. This retrospective cohort study analyzed 72 eyes from 72 consecutive patients after MIOL surgery . To investigate magnitude and axis of astigmatic changes, the concepts of true corneal astigmatism and Alpins vector method were applied. There were no statistically significant between-group differences prior to surgery...

PURPOSE: Many different models and types of special intraocular lenses (IOL) are now available for refractive lens surgery. In particular, toric and multifocal IOL need specific conditions to achieve satisfactory results. For multifocal IOL, many models with different optical principles are available. For optimal individual patient-centred care, it is necessary to consider several different options. With special refractive lenses, the principle objective for the patients is to become less dependent on glasses...

BACKGROUND/AIM: The purpose of the present study was to evaluate clinical outcomes and optical performance of 4 different multifocal intraocular lenses (IOLs). MATERIALS AND METHODS: Ninety eyes of 51 patients who received Reviol MFM 611, Reviol MFM 625, Acri.LISA, and ReSTOR SN6AD3 multifocal IOLs after cataract surgery were retrospectively evaluated. The patients were similar in terms of age, sex, cataract hardness and axial length. The mean outcome measures were uncorrected and corrected distance visual acuity (UDVA, CDVA), distance-corrected intermediate and near visual acuity (DCIVA, DCNVA), intra or postoperative complications, and contrast sensitivity (CS) results under mesopic conditions...

PURPOSE: To evaluate functional results and reading performance using the Salzburg Reading Desk after implantation of a sector-shaped near-embedded, rotational asymmetrical multifocal intraocular lens (IOL) and a multifocal toric IOL with a +3.00 diopter (D) near addition. METHODS: In a prospective study, the LentisMplus and Mplus toric IOLs (Oculentis GmbH, Berlin, Germany) were implanted in 34 eyes of 18 patients at the University Eye Hospital of Heidelberg. Uncorrected and corrected distance visual acuity (UDVA, CDVA) and uncorrected and corrected near visual acuity (UNVA, CNVA) were evaluated using standardized visual acuity charts (ETDRS)...

PURPOSE: To report findings that could suggest an elliptical shape of the capsular bag. METHODS: Five eyes of three patients with axial length greater than 24 mm underwent phacoemulsification cataract surgery with plate-haptic multifocal toric intraocular lens (IOL) implantation oriented in the vertical meridian. RESULTS: In all cases, correct orientation of the IOLs was verified 30 minutes after surgery. After 24 hours, all eyes demonstrated unwanted rotation of the IOLs ranging from 15 to 45 degrees...

UNLABELLED: We present a technique that uses a near-point string to demonstrate the anticipated near point of multifocal and accommodating intraocular lenses (IOLs). Beads are placed on the string at distances corresponding to the near points for diffractive and accommodating IOLs. The string is held up to the patient's eye to demonstrate where each of the IOLs is likely to provide the best near vision.
