Multifocal-toric IOL Compared to Multifocal IOL Combined With Limbal Relaxing Incisions for Correction of Moderate Astigmatism During Cataract Surgery

Multifocal-toric IOL Compared to Multifocal IOL Combined With Limbal Relaxing Incisions for Correction of Moderate Astigmatism During Cataract Surgery: A Randomised Trial

The purpose of the present study is to compare the outcome of multifocal toric intraocular lens with standard multifocal lens plus incisional surgery in patients undergoing bilateral cataract surgery.

This is a randomized controlled trial with intra-patient comparison, 60 eyes (30 patients) with cataract and corneal astigmatism of 1.00 to 2.50 D (doctrine) took part in the trial. The trial assessed the efficacy of multifocal IOL (intraocular lens) with corneal pre-existing astigmatism and compare the outcomes of a multifocal toric IOL or a standard multifocal IOL combined with limbal relaxing incisions.

Inclusion Criteria:

• Bilateral cataract and be planning to have both eyes operated on.
• Age 21 and older
• Have cataracts that allow IOL master biometry
• Regular corneal astigmatism 1.00 up to 2.50 D
• Difference of corneal astigmatism in both eyes to be equal to or less than 0.75D
• written informed consent to surgery and participation in the study
• Speak English

Exclusion Criteria:

• Relevant other ophthalmic diseases such as: pseudoexfoliation, glaucoma, traumatic cataract corneal scars, and other co-morbidity that could affect capsule bag stability ( e.g. Marfan syndrome)
• Irregular corneal astigmatism on Pentacam topography
