Abstract Details

Purpose:

To compare outcomes of femtosecond laser anterior capsulotomy and laser phacofragmentation (Femto) with the outcomes of traditional standard lens implantation procedures (Std) and corneal incisions [LRI] in astigmatic eyes treated at the same hospital group over the same period.

Setting:

Optegra Eye HealthCare Hospitals UK.

Methods:

Observational retrospective case series of 100 (Femto) 134 [LRI] and 394 (Std) eyes. Outcomes were compared between groups of eyes treated with FLACS and standard procedures and implanted with toric multifocal IOLs, and astigmatic eyes implanted with non-toric IOLs and corneal incisions.

Results:

Vector analysis of astigmatism was carried out within the three groups. There were no significant differences between target induced astigmatism and surgically induced astigmatism in the [Femto] or [Std] of the groups. Residual astigmatism was within ±0.50 of target in 77% of eyes in the [Femto] and [Std] groups, but 37% in the LRI group [p<0.05]. Mean Correction Index in the [Femto] group was 1.16, in the [Std] group was 1.21 and in the LRI group was 1.42 [p<0.05]

Conclusions:

This relatively large-scale study appears to demonstrate that the outcomes of the femtosecond laser group and the standard group were equivalent in terms of effectivity and predictability of the correction of astigmatism, and significantly more effective and predictable than in treatments using LRIs.
