Purpose:

Compare the outcomes of a new accommodating IOL to a well-defined, trifocal diffractive IOL

Methods:

Nineteen subjects were randomized to receive either bilateral, sequential accommodating IOLs or bilateral, sequential trifocal IOLs. Ten subjects received the accommodating AIOLs and nine received the trifocal IOLs. The age range of the subjects was 54 to 75 yo. Subjects were followed up at 1 day, 1 week and at 1, 3, and 6 months. Visual acuities (distance, intermediate (66 cm) and near (40 cm), contrast sensitivity, and refraction were obtained by a masked optometrist.

Results:

All surgeries were uneventful. The mean acuities at 3 months for the patients with the accommodating IOLs were 0.18 +/- 0.19, 0.09 +/- 0.10 & 0.20 +/-0.17, UCDVA, distance corrected intermediate & near respectively. The mean acuities for the trifocal IOLs were 0.15 +/- 0.16, 0.22 +/- 0.12 & 0.19 +/- 0.12, UCDVA, distance corrected intermediate & near respectively. The intermediate vision was significantly better (p<0.008) for="" the="" accommodating="" iol.="" the="" distance="" corrected="" near="" visual="" acuity="" with="" a="" 10%="" contrast="" target="" was="" measured="" at="" 0.53="" +/-="" 0.22="" for="" the="" accommodating="" iol="" and="" at="" 0.72="" +/-="" 0.15="" for="" the="" trifocal="" iol="" for="" a="" two="" line="" improvement="" with="" the="" accommodating="" iol="" over="" the="" trifocal="" iol.="" for="" the="" accommodating="" iol.="" the="" distance="" corrected="" near="" visual="" acuity="" with="" a="" 10%="" contrast="" target="" was="" measured="" at="" 0.53="" +/-="" 0.22="" for="" the="" accommodating="" iol="" and="" at="" 0.72="" +/-="" 0.15="" for="" the="" trifocal="" iol="" for="" a="" two="" line="" improvement="" with="" the="" accommodating="" iol="" over="" the="" trifocal="">

Conclusions:

This is the first reported direct comparison of a shape changing accommodating IOL against a high quality, diffractive trifocal IOL. The results show the two IOLs are equivalent at distance and hear with high contract acuity targets. The accommodating IOL showed better results at intermediate with high contrast and near with low contrast.
