Abstract Details

Purpose:

To compare visual outcome of a new monofocal, acrylic hydrophilic aspheric intraocular lens (IOL) I-Stream H (MD Tech, Casoria, Italy) with monofocal acrylic hydrophobic spheric CT Lucia 211P (Carl Zeiss Meditech, Jena Germany) in patients undergoing cataract surgery.

Setting:

Università degli Studi “Magna Graecia”, Catanzaro, Italy.

Methods:

Sixty-six consecutive patients undergoing cataract surgery were randomly selected to receive I-Stream (Group 1) or CT Lucia (Group 2) IOL. Patients of both groups underwent a complete eye examination, ocular biometry (IOLMaster 500, Zeiss, Germany), contrast sensitivity test (CST) and visual function questionnaire (VF-14) before surgery. Intra- and postoperative complications, refraction, visual acuity (logMAR), CST score and VF-14 one were recorded at 1, 3 and 6 months follow up. Differences among parameters of the two groups of patients were evaluated with non-parametric Mann-Whitney test; paired Student t test was used for paired data using SPSS software.

Results:

There was not significant difference (p = 0.21) in the mean postoperative best correct visual acuity (BCVA) at 6 months follow up, comparing results obtained in group 1 (mean: 0.02 ± 0.12 logMAR) with group 2 (mean: 0.02 ± 0.09 logMAR) eyes. At 6-month follow up, differences in refraction (0.05 ± 0.28 D; p= 0.14), in contrast sensitivity score (0.03 ± 0.07 cd/m2; p= 0.09) and in VF score (mean 1.75 ± 0.87, p = 0.16) were not significant between eyes of group 1 and group 2. No complications were recorded in both groups.

Conclusions:

According to data observed in this study, although they need to be confirmed in further ones with longer follow up and larger population, both IOLs evaluated provide very good outcome in terms of BCVA, contrast sensitivity and visual function in patients undergoing cataract surgery with comparable level of safety.
