Purpose

To present the outcome of a new automatic Diode Laser capsulotomy technique performed in 0.23 seconds.

Setting

Vissum Grupo Miranza, University Miguel Hernandez, Alicante, Spain.

Methods

39 eyes of 30 consecutive patients were included. Following capsular staining with microfiltered trypan blue 0.4%, the anterior capsulotomy was performed in 0.23 sec. The laser device, mounted to the operating microscope, focused on the anterior capsule and Purkinje image (PI). Intraoperative and postoperative examinations were used to assess efficacy, reliability and safety (accuracy of capsulotomy size, circularity, centration, resistance, Intra-Ocular lens (IOL) centration) and postoperative fibrosis.

Results

A variety of cataracts were included . Capsulotomies were selected to be 5 mm in diameter on the corneal plane & centered on the PI with ease. The measured capsulotomy diameter was (5 V×5 H) with a standard deviation of 0.2 mm. Circularity accuracy was excellent in 82%(32) achieving a free cap, while 18%(7) had some remnant tags (<4 tags); secondary to sudden eye rolling & completed manually. Capsular edge resistance was excellent in 97%(38) and 3%(1) had a tear, coinciding with weak zonules and managed intraoperatively. All IOLs inserted, 19 premium, were perfectly centered and stable. The IOL–capsulotomy overlap was 360 degrees in all. Patients were followed up for at least 3 months and no fibrosis or decentration were noticed.

Conclusions

0.23 seconds automatic laser capsulotomy using a new Trypan blue formulation and Diode laser was safe and effective in cataract surgery. The sizing, circularity and centration of the laser capsulotomy were accurate.
