Abstract Details

Purpose:

To compare the post-operative visual acuity and refractive outcome and complication rates after implantation of a multifocal intraocular lens (IOL) when applying a femto-second laser for capsulotomy and crystalline lens fragmentation and performing these steps manually.

Setting:

Optegra Eye Hospital Manchester, Manchester, UK

Methods:

In a retrospective analysis the outcome of 259 eyes that underwent IOL implantation after manual capsularhexis and without crystalline lens fragmentation were compared to 307 eyes that underwent IOL implantation using Lensar for capsulotomy and crystalline lens fragmentation. All surgeries were performed by a single surgeon (SAQ). Age distribution was similar in both groups: mean age at surgery ± standard deviation in the Non-Lensar group was 61±7 years and 61±8 years in the Lensar group. In the Non-Lensar group the gender distribution was: 74% females and 26% males, in the Lensar group it was 66% females and 23% males.

Results:

In the Lensar group 95% of eyes achieved 6/12 or better UDVA post-operatively and in the Non-Lensar group the figure was 96%. 58% and 53% of eyes could see 6/6 or better UDVA in the Lensar and Non-Lensar groups, respectively. For spherical equivalent refraction 96% of eyes in the Lensar group and 97% in the Non-Lensar group were within ±1.00D. 88% of eyes in the Lensar group and 84% in the Non-Lensar group were within ±0.50D. No operative complications occurred in either group. In the Lensar group 84% of eyes were free from post-operative complications and in the Non-Lensar group the figure was 82%.

Conclusions:

Both approaches provide similarly good results for post-operative refraction and unaided monocular distance visual acuity. More importantly both approaches were similarly safe in terms of complication rates.
