Abstract Details

Purpose:

To report the visual, refractive outcomes and surgically induced astigmatism (SIA) following biaxial micro incision (1.3 mm) cataract surgery (B-MICS) with implantation of a new aspheric hydrophilic intraocular lens.

Setting:

University Hospital Ayr,Scotland,United Kingdom

Methods:

Prospective interventional case series. 43 eyes of 43 patients underwent B-MICS through a 1.3 mm clear corneal incision by a single surgeon. Data on optical biometry, keratometry, pre and post-operative unaided distance visual acuity (UDVA) and post operative corrected distance visual acuity (CDVA) were collected. Post operative keratometry was performed in all cases at four weeks time gate. Commercially available software was used to calculate SIA.

Results:

There were no intra-operative complications. LogMAR median post-operative UDVA and CDVA were 0.01 and 0 respectively. Post operative median spherical equivalent (MSE) was plano. The median absolute difference between predicted and actual MSE was 0.26 Dioptres (D). Mean numerical SIA was 0.2 D. Analysis of astigmatic vectors found no statistically significant difference between pre and post-operative keratometric values.

Conclusions:

Bi-axial MICS using the Incise IOL through a 1.3mm clear corneal incision results in minimal surgically induced astigmatism and can facilitate good post-operative visual function with predictable refractive outcomes. FINANCIAL INTEREST: NONE
