Abstract Details

Purpose:

Comparison between standard Phakoemulsifikation and Nano Laser Photofragmentation in a randomised , prospective clinical trial with regard to the amount of surgical trauma

Setting:

Charlottenklinik

Methods:

60 patients were randomely distributed in a Nano Laser (NL) and a phako group (PH). Routine cataract surgery was performed by one experienced surgeon under topical anesthesia. Density of the cristaline lens was preoperatively staged according to the LOCS grade system – limitation of nuclear density was limited to +3. Main outcome measurements were pachymetry and endothelial cell count. Duration of surgery and infusion in ml per surgery were measured.

Results:

Duration of surgery was 5.14 min (PH) and 7.26 min in the NL group. The use of BSS was 25% higher in the NL group. The decrease in pachymetry at day 1 was 36.4 ± 30.2µm (PH) and 24.2 ± 18.0 µm (NLP). There was no significant difference in both groups concerning increase of visual acuity, postoperative IOP and complications

Conclusions:

The Nano Laser photofragmentation is a safe surgical technique with very low emission of energy into the eye. Positive results of the nano laser group compared to phako with regard to pachymetry and endothelial cell count has to be proved in more patients and in longer follow up period.
