Abstract Details

Purpose:

Irregular corneal astigmatism leads to decreased vision and poor vision due to higher-order refractive errors. A new IOL (Acufocus IC-8) including a pinhole optical function could correct for irregular corneal astigmatism in patients undergoing cataract surgery.

Setting:

University Eye Hospital Munich

Methods:

Prospective non-randomized monocentric interventional case series of patients with irregular corneal astigmatism and significant cataract. Inclusion criteria were best-corrected Snellen VA ≤ 0.7, patient age ≥ 45 years, and intolerance of wearing contact lenses. Severe or progressive keratoconus> 55D, unstable zonules or PEX, glaucoma, maculopathy, central corneal scars and a reduced endothelial cell count <1800 cells / mm2 were excluded. The uncorrected and best corrected visus for the distance, intermediate and near range, as well as a defocus curve was determined. Quality of life was assessed using a modified VFQ-25 questionnaire.

Results:

The uncorrected and best corrected visual acuity for the distance, intermediate and near range improved significantly. The defocus curve showed an extended focus area postoperatively. There were no safety-related events intra- and postoperatively. The quality of life in relation to activities both near and far increased 3 months postoperatively. Different biometric formulas of newer generations must be considered for the individual IOL power calculation.

Conclusions:

The implantation of a new IOL with pinhole function (IC-8) in the cataract surgery of patients with irregular corneal astigmatism is a safe and effective procedure
