Abstract Details

Purpose:

To investigate and evaluate the current safety, efficacy and surgical outcomes of femtosecond laser-assisted cataract surgery in Japanese eyes and suggest the related issues for possible future improvement of the technique.

Setting:

Nishi Eye Hospital, Osaka, Japan

Methods:

41 eyes with senile cataract were randomly selected to undergo femtosecond laser assisted cataract surgery. A total of 26 eyes underwent cataract surgery, in which CCC(4.8mm) as well as lens fragmentation was done by means of femtosecond laser system(Catalys, OptiMedica). Surgical outcomes as well as complications were prospectively investigated.

Results:

The preoperative uncorrected distant visual acuity (UCDVA), corrected distant visual acuity (CDVA), IOP, flare, corneal endothelial cells count, and spherical equivalent (SE) was 0.21+/_0.20, 0.66+/_0.29, 12.5+/_2.2 (mmHg), 7.7+/_0.1, 2585+/_277 (cells per square millimeter), and -3.2+/_6.0 each. 1 week postoperatively, UCDVA, CDVA, IOP, flare, and SE turned out to be 0.78+/_0.34, 1.1+/_0.33, 12.5+/_3.8 (mmHg), 16.3+/_9.6, -0.65+/_1.0 each. There were 16 cases, in which the suction cup for docking of the eye with the laser system could not be successfully set on the ocular surface, simply due to anatomical reasons. In 2 cases, CCC was almost completed but not completely, the one of which case led to total rupture of posterior capsule without any significant sign.?The sample size as well as the outcomes and complications will be updated.

Conclusions:

The surgical outcomes may not differ significantly from those by standard cataract surgery. This technology, however, would have a great potential to make cataract surgery constantly safer with less stress or surgical experiences by surgeons at least in non mature cataract cases, and possibly even the efficacy, which is the current issue, may be less problematic with future systematic and technological improvement.
