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 < 0.05); the binocular uncorrected distance visual acuity and best spectacle-corrected visual acuity remained unchanged; manifest refraction spherical equivalent was significantly reduced from 0.01 ± 0.68 D preoperatively to -1.68 ± 0.39 D (P < 0.05); spherical aberration was increased from 0.266 ± 0.204 µm preoperatively to 0.358 ± 0.277 µm (P < 0.05), and pseudoaccommodation was from 1.38 ± 0.38 D to 1.73 ± 0.61 D (P < 0.05). CONCLUSIONS: Conductive keratoplasty is a safe and effective method for relief of symptomatic presbyopia of pseudophakia with monofocal intraocular lens implantation.
