  2. Purpose • To report the postoperative outcome and patient satisfaction with the new diffractive multifocal IOL used in eyes which underwent phacoemulsification

  3. Material / Methods • This prospective study included patients with age-related cataract and unsatisfactory correction with glasses. • Information collected included uncorrected visual acuity (UCVA) for near and distance, best corrected visual acuity (BCVA), and spherical equivalent (SE) before and after the surgery, and patient satisfaction.

  4. Material / Methods TECNIS™ Product Specifications (Model ZM900) • Modified prolate anterior surface • Square-edge optic • Diffractive multifocal posterior surface • UV-absorbing 6.0 mm optic • Polyvinylidene flouride (PVDF), CapC haptics • 5 D to 34 D in 0.5 D increments • 3-piece foldable for posterior capsular bag fixation

  5. Results • Six hundred and forty four eyes of 363 patients were enrolled in the study and underwent implantation with the Tecnis multifocal IOL. • Of the 363 patients, there were 245 (68%) females and 118 (32%) males. • The mean age of the patients was 62 years, range from 47 to 91 years old (SD: ± 8.7) • All postoperative visual acuity results were obtained at the 3-month postoperative visit.

  6. Results • Preoperatively, the mean distance UCVA of these eyes was 0.25 (20/80) (range 0.01 to 1.00, SD = ± 0.36). • After follow-up of 3 months the mean UCVA was 0.8 (20/25) (range 0.13 t0 1.00), significantly better than before surgery (p<0.001). • After a follow-up of 3 months a distance UCVA of 20/25 or better was achieved by 74.2% (478 of 644 eyes), and a distance UCVA of 20/40 or better was achieved by 94.5% (609 of 644 eyes).

  7. Results • Preoperatively, the mean distance BCVA of these eyes was 0.67 (20/30) (range 0.05 to 1.0, SD = ± 0.29). • After follow-up of 3 months the mean BCVA was 1.0 (20/20) (range 0.33 to 1.00), significantly better than before surgery (p<0.001). • The average SE at referral of these eyes was + 0.95 D (range -12.5 to + 12.25 D, SD: ± 2.28). • Postoperatively, after a follow-up of 3 months the average SE was -0.10 D (range -2.25 to +1.75, SD: ± 0.48), significantly better than before referral (p<0.001).

  8. Results • After follow-up of 3 months the mean uncorrected near vision acuity (UCNVA) was J1 (range to J1 to J4). • After follow-up of 3 months a near UCVA of J1 or better was achieved by 93.7% (604 of 644 eyes), and a near UCVA of J3 or better was achieved by 99.8% (643 of 644 eyes). • In addition, 96.2% and 94.3% of the patients achieved spectacle independence for distance and near vision, respectively. • Visual phenomena was observed by 33.3% of the patients. Glare and halos were reported as severe by 3.5% of patients, moderate by 14.6%, and mild by 15.1% of patients.

  9. Conclusion • The TECNIS diffractive multifocal IOL demonstrated excellent near VA without compromising distance vision. Spectacle independence and patient satisfaction were high, whereas unwanted photic phenomena were clinically acceptable.
