Purpose

The purpose of the present study was to assess the outcomes of intrastromal femtosecond laser-assisted astigmatic keratotomy for the correction of low degrees of corneal astigmatism using iris registration at the time of cataract surgery

Setting

Oftalvist, Alicante, Spain

Methods

This single-center prospective study was approved by the Ethics Committee of the Hospital General Universitario (Alicante, Spain) and registered at www.clinicaltrials.gov (registration number: NCT05053620). A femtosecond laser-assisted astigmatic keratotomy nomogram with 9.0 mm diameter paired symmetric centered incisions arcs from 50 to 65 degrees was used to correct from 0.50 to 1.25D corneal astigmatism. Corneal keratometry, refraction and visual acuity were measured preoperatively and 4 months postoperatively. Astigmatism vector analyses was performed using the double-angle and corneal surgically induced astigmatism from the American Society of Cataract and Refractive Surgery website online tools. 

Results

Femtosecond laser-assisted astigmatic keratotomy was performed with the Catalys cOS 6 Precision System (Johnson & Johnson Vision Care, Santa Ana, CA, USA) using the Cassini Ambient (Cassini Technologies B.V, Den Haag, The Netherlands) with iris registration at the time of cataract surgery. Cataract surgery was done by means a standard phacoemulsification procedure using the Centurion system (Alcon, Fort Wort, TX, USA) and eyes were implanted with the monofocal Tecnis ZCB00 intraocular lens (Johnson & Johnson Surgical Vision Care, Santa Ana, CA, USA). 33 eyes were considered for this study.

Conclusions

This prospective non-randomized interventional case series study will show the safety and efficacy of femtosecond laser-assisted astigmatic keratotomy for the correction of low degrees of corneal astigmatism using the Catalys femtosecond laser-assisted platform linked to the Cassini Ambient with iris registration at the time of cataract surgery.
