Laser corneal enhancement after trifocal intraocular lens implantation in eyes that previously had photoablative corneal refractive surgery

To evaluate the visual and refractive outcomes of laser corneal enhancement after trifocal intraocular lens (IOL) implantation in eyes previously treated with myopic/hyperopic laser corneal refractive surgery (LCRS).Clinica Baviera-AIER-Eye Group, Spain.Retrospective comparative case series.Patients were divided by primary LCRS into myopic and hyperopic groups. The outcomes evaluated were uncorrected distance (UDVA), corrected distance (CDVA), uncorrected intermediate (UIVA), and uncorrected near visual acuity (UNVA), and predictability, safety, efficacy, and satisfaction after implantation of 2 trifocal IOL models (Physiol-FineVision and Zeiss-ATLisa 839) and subsequent laser enhancement.186 eyes (89 myopic and 97 hyperopic eyes) from 146 patients were assessed. At the last visit, refractive outcomes were better in myopic than those in hyperopic eyes, with statistically significant differences for sphere ( P.001), cylinder ( P.001), manifest refraction spherical equivalent (MRSE) ( P = .003), CDVA ( P = .005), UDVA ( P = .047), and UNVA ( P = .003) but not for UIVA ( P = .580), binocular UIVA ( P = .660), or binocular UNVA ( P = .836). Predictability differences were nonsignificant between groups for a final MRSE of ±0.5 diopters (D) and ±1.0 D (P = .167 and .502, respectively). Efficacy and safety were similar in both groups ( P = .235 and P = .080). A greater myopic MRSE was present after trifocal implantation in myopic than in hyperopic eyes (MRSE = -0.93 vs -0.69 D, P = .013), and the statistically significant differences were maintained after enhancement between both groups (MRSE -0.00 vs 0.00 D, P = .003). Overall satisfaction was similar in both groups ( P.05 all items).Corneal laser enhancement after implantation of a trifocal IOL in eyes previously treated for myopia or hyperopia with LCRS was safe, effective, predictable, and highly satisfactory.
