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

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 (plt0.001).
• 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 (plt0.001).
• 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 (plt0.001).

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.

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.
