Visual Outcomes of a Segmental Refractive Multifocal Intraocular Lens

Visual Outcomes After Implantation of a Segmental Refractive Multifocal Intraocular Lens Following Cataract Surgery

To evaluate visual outcomes of a segmental refractive multifocal intraocular lens (IOL) after cataract surgery.

Purpose: This prospective, nonrandomized noncomparative case series investigates the visual performance after bilateral implantation of a segmental refractive multifocal intraocular lenses (IOL) after cataract surgery and was performed at the department of Ophthalmology, Goethe University, Frankfurt, Germany.

Methods: Fifty eyes (25 patients) were included. Inclusion criteria were bilateral cataract, age > 45 years, corneal astigmatism ≤ 0.75 D postoperatively, pupil size 3 to 6 mm (mesopic), and center shift < 1 mm (Pentacam). Exclusion criteria were previous ocular surgeries, amblyopia or potential postoperative distance-corrected visual acuity (DCVA) < 0.3 logMAR,

Intervention or Observation: Uncorrected (UCVA) and DCVA in 4 m, 80 cm, 40 cm; contrast sensitivity (CS) under photopic and mesopic conditions; reading skills (Radner Reading Charts); defocus curve, questionnaire on optical quality (OQ) and spectacle independence were assessed after 3 months.

Main Outcome Measures: At 3 months postoperatively, UCVA and DCVA in 4 m, 80 cm, 40 cm (logMAR); defocus curves; CS; reading skills; and OQ questionnaire results.

Inclusion Criteria:

• bilateral cataract
• age > 45 years
• corneal astigmatism ≤ 0.75 D postoperatively
• pupil size 3 to 6 mm (mesopic)
• center shift < 1 mm

Exclusion Criteria:

• previous ocular surgeries
• amblyopia
• potential postoperative distance-corrected visual acuity (DCVA) < 0.3 logMAR
