Official title
Safety and Efficacy of Astigmatism Correction by Iris-registration Guided Corneal Relaxing Incisions or Toric IOL Implantation During Femtosecond Laser-assisted Cataract Surgery
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Most of the patients presenting for cataract surgery also have pre-existing corneal astigmatism which if left uncorrected can adversely affect visual and refractive outcomes after cataract surgery. Pre-existing astigmatism at the time of cataract surgery can be corrected by either corneal relaxing incisions or implantation of toric IOLs. While the safety and efficacy of these procedures are well established, there are various challenges associated with these techniques that surgeons need to overcome to achieve good outcomes postoperatively. The use of iris registration technology that automatically compensates for cyclotorsion has the potential to improve the alignment accuracy of CRI or toric IOLs. The Cassini Ambient and Catalys Femtosecond Laser incorporate this technology to help cataract surgeons accurately align toric IOLs on the intended axis of implantation or accurately place CRI on the intended meridian. The present study is aimed at evaluating the efficacy of astigmatism correction during femtosecond laser-assisted cataract surgery with Catalys femtosecond laser. The patients will either undergo iris registration guided CRIs or iris registration guided alignment of toric IOLs.
