Study summary

This is an observational, prospective follow-up post-marketing study of CE marked medical devices aimed at treating astigmatism in patients with cataracts. The main objective is to evaluate the response of the intrastromal arcuate incisions procedure for the correction of low corneal astigmatism with the Catalys femtosecond laser using the Cassini Ambient equipment with iris registration in cataract surgery.

Read the detailed description

All patients participating in the study will undergo femtosecond laser treatment for the correction of astigmatism through arcuate intrastromal incisions with the Catalys laser (Johnson \& Johnson, USA, CE marked). The calculation of intrastromal arcuate incisions will be carried out using the following nomogram indicated on the laser: 9.0 mm optical zone and symmetrical incisions of 50 degrees for 0.50D, 55 degrees for 0.75D, 60 degrees for 1.00D and 65 degrees for 1.25D of corneal astigmatism. After the incisions, conventional cataract surgery will be performed using the Centurion phacoemulsifier equipment (Alcon, USA, with CE marking) in the ZCB00 monofocal intraocular lens (IOL) implant (Johnson \& Johnson, USA, with CE marking). All patients will be treated according to standard clinical practice.

A preoperative and postoperative evaluation will be carried out one month and four months after the intervention where the following tests will be performed: refraction, corneal topography with the Cassini Ambient equipment (Cassini Technologies, The Netherlands, with CE marking), measurement of visual acuity with and without correction, slit lamp examination and ocular biometry using the IOLMaster 700 non-contact optical biometer (Carl Zeiss, Germany, CE marked).
