Conductive keratoplasty for symptomatic presbyopia following monofocal intraocular lens implantation

Background: To evaluate the visual outcomes of conductive keratoplasty for relief of symptomatic presbyopia of pseudophakia with monofocal intraocular lens implantation. Design: It was a prospective clinical study and set in Eye Center, Second Affiliated Hospital, Zhejiang University. Participants: This study comprised 27 eyes from 27 patients with presbyopia symptom. Methods: The patients received conductive keratoplasty via monovision approach after monofocal intraocular lens implantation and were followed up at 1 week and 1, 3, 6 and 12 months postoperatively. Main Outcome Measures: The main outcomes including uncorrected near visual acuity, uncorrected distance visual acuity, best spectacle-corrected visual acuity, manifest refraction spherical equivalent, keratometric astigmatism, contrast and glare sensitivity, spherical aberration and pseudoaccommodation were evaluated. Results: Twelve months after conductive keratoplasty, the binocular uncorrected near visual acuity was significantly improved from logMAR 0.88 ± 0.16 preoperatively to logMAR 0.30 ± 0.13 (P
