OCT-guided femtosecond laser increases safety, accuracy of Kamra inlay
Real-time optical coherence tomography-guided femtosecond laser technology increased safety and accuracy of the Kamra corneal inlay in patients with history of LASIK, according to a study.
“An important advantage is that femtosecond laser pulse can be placed individually at different locations within the cornea, allowing accurate cuts and adjustment of individual cut patterns, more stable corneal and visual outcomes, and better surgical safety,” the authors wrote in the study.
The retrospective study included 151 presbyopic eyes that underwent Kamra corneal inlay (AcuFocus) using real-time OCT-guided femtosecond laser technology (Ziemer) for creation of the pocket. All patients had history of prior LASIK surgery.
Patients underwent examinations at 1 day, 1 week, 1 month and 3 months after surgery to evaluate visual outcomes.
Mean manifest refraction spherical equivalent changed from −0.18 to −0.95, and uncorrected distance visual acuity (UDVA) changed from 20/16 to 20/20; uncorrected near visual acuity changed from J8 to J2, the researchers found.
Results showed that 7.9% of eyes lost one line of corrected distance visual acuity, 19.2% of eyes lost one line of UDVA and 18.5% of eyes lost two lines of UDVA.
