Abstract

Purpose: To compare visual outcomes of eyes that had laser refractive surgery with the Contoura Phorcides treatment plan and eyes that had laser refractive surgery with the wavefront-optimized treatment plan using the same laser.

Methods: Retrospective chart review of clinical outcomes of eyes that had either Contoura with Phorcides (CP) or wavefront-optimized (WFO) corneal refractive procedures using the Wavelight EX500 (Alcon Vision, LLC). Data were collected and compared for uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), refraction, change in postoperative UDVA compared to preoperative CDVA, and change in postoperative CDVA compared to preoperative CDVA.

Results: Total eyes included were 348, with 227 in the CP Group and 121 in the WFO Group. Post-operatively, there was a significantly higher percentage of eyes in the CP Group that were 20/16 or better compared to the WFO Group (57%, 129 eyes, and 17%, 21 eyes, respectively; p < 0.001). The percentage of eyes that gained 1 or more Snellen lines of UDVA compared to preoperative CDVA was higher in the CP Group (47%; 107 eyes) compared to the WFO Group (12%; 14 eyes), which was statistically significant (p < 0.001). Differences in refraction were statistically significant.

Conclusion: Topography-guided and wavefront-optimized treatment profiles both provided excellent refractive results. A higher percentage of eyes that were treated using Contoura with Phorcides achieved 20/16 or better unaided distance vision compared to eyes receiving a wavefront-optimized treatment plan.

Keywords: Contoura; Phorcides; topography-guided LASIK; wavefront-optimized LASIK.

Plain language summary

Laser in situ keratomileusis (LASIK) is a common procedure performed to reshape the cornea (transparent part of the eye) and provide clear, spectacle-free vision. There are many different technologies available for surgeons to choose a treatment plan. One of the most popular is called wavefront-optimized LASIK (WFO), which takes into account the curvature of the cornea. Recently, topography-guided LASIK treatment plans that incorporate a proprietary planning software (Contoura Phorcides) have been available that can factor in the individualized surface elevation characteristics of the cornea. The purpose of this study was to compare visual outcomes in patients that had LASIK with the Contoura Phorcides treatment plan to patients that had LASIK with the WFO treatment plan. The results of this study suggest that both treatment profiles both provided excellent refractive results. In addition, a higher percentage of eyes that were treated using Contoura with Phorcides achieved 20/16 or better unaided distance vision compared to eyes receiving a WFO treatment plan.
