About

This study evaluated visual outcome after cataract surgery with bilateral implantation of either a diffractive - refractive (hybrid) multifocal intraocular lens (MFIOL) or monofocal intraocular lens (IOL) as a control grup.

Full description

PURPOSE: To present the outcomes of hybrid multifocal and monofocal intraocular lenses (IOL)

SETTING: Parc de Salut Mar, Universidad Pompeu-Fabra - Autónoma, Barcelona, Spain.

DESIGN: Prospective clinical trial.

METHODS: Consecutive patients with bilateral cataract were included. Phacoemulsification with randomized implantation of either a monofocal IOL (AR40e, AMO-Abbot 30 Laboratories Inc. Abbot Park, Illinois, USA) or multifocal IOL (OptiVis™, Aaren Scientific, Inc, Ontario, CA, USA) was performed by the same surgeon and under the same conditions. Over a 3-month follow-up, the main outcome measures were uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), uncorrected intermediate visual acuity at 60 cm (UIVA), distance-corrected intermediate visual acuity (DCIVA), uncorrected near visual acuity at 33 cm (UNVA), distance-corrected near visual acuity (DCNVA), spherical equivalent (SE), contrast sensitivity (CS), presence of dysphotopsia, use of spectacles and patient satisfaction with the test VF-14 (Visual Function Index) .

Inclusion criteria

  • senile cataract with Snellen visual acuity ≤ 0.5,
  • motivation for spectacle independence for near vision (as the study was conducted in Spanish public health care system, entering study was the only option to get multifocal lens, as they are not provided by public health care, and the patients were conscious of the possibility of randomization to monofocal group.)

Exclusion criteria

  • corneal astigmatism ≥ 1.10 diopters (D) and irregular astigmatism,
  • axial length < 21.5 or ≥ 25 mm,
  • pupillary diameter in mesopic conditions in distance vision ≤ 2.5 mm and ≥ 6 mm,
  • ocular pathology that could affect the visual function and/or intraocular lens centering and intraoperative or postoperative complications.
  • highly demanding patients and those whose profession could be affected by a multifocal design (professional drivers, jewelers etc.) were also excluded (as in the Spanish public health care system secondary procedures needed to satisfy patients' expectation, such as LRI´s, LASIK, PRK´s, are not available).

32 participants in 2 patient groups

Multifocal IOL (OptiVis)
Experimental group
Description:
Ambulatory surgery was performed by the same, experienced surgeon, under topical anesthesia, using as a technique phacoemulsification with small incision (2.75) in clear cornea in the most curved meridian. The randomly assigned IOL (in this arm: a hybrid (refractive-diffractive) multifocal IOL (OptiVis, Aaren Scientific) was implanted in the capsular bag. The second eye with the same type of lens of the first eye was operated within 2-4 weeks.
Treatment:
Device: OptiVis, Aaren Scientific
Monofocal IOL
Active Comparator group
Description:
Ambulatory surgery was performed by the same, experienced surgeon, under topical anesthesia, using as a technique phacoemulsification with small incision (2.75) in clear cornea in the most curved meridian. The randomly assigned IOL (in this arm: a monofocal IOL (AR40e, AMO) was implanted in the capsular bag. The second eye with the same type of lens of the first eye was operated within 2-4 weeks.
Treatment:
Device: Monofocal IOL
