Refractive and Visual Outcomes With the ARGOS Biometer In Eyes With a History of Refractive Surgery: ARGOS Study

Refractive and Visual Outcomes With the ARGOS Biometer In Eyes With a History of Refractive Surgery: ARGOS Study

The study is to evaluate the visual and refractive outcomes in eyes with prior myopic refractive surgery undergoing cataract surgery for intraocular lens (IOL) power calculations.

This was a prospective, single-site, study evaluating the accuracy of the ARGOS biometer in subjects with a history of myopic corneal refractive surgery including Laser-Assisted In Situ Keratomileusis (LASIK) and Photorefractive Keratectomy (PRK).

Inclusion Criteria:

• Patients undergoing uncomplicated cataract surgery with a history of myopic corneal laser refractive surgery
• Subjects electing to undergo implantation with a monofocal/non-toric IOL
• Willing and able to comprehend informed consent and complete an 8-week visit.
• Potential postoperative Corrected Distance Visual Acuity (CDVA) of 20/20 or better in each eye based on Investigator's medical opinion

Exclusion Criteria:

• Concurrent or prior ocular surgery within the previous 12 months.
• Ocular comorbidity that could reduce the potential postoperative CDVA based on the discretion of the operating surgeon
• History of hyperopic laser corneal refractive surgery
• History of radial keratotomy
• Irregular corneal astigmatism or keratoconus 6. Eyes with intraoperative or postoperative complications 7. Eyes with BCDVA worse than 20/100 preoperatively 8. Subjects who are pregnant or plan to become pregnant during the course of the study.
