Abstract Details


To assess clinical outcomes and patient satisfaction after bilateral implantation of a diffractive trifocal intraocular lens(IOL).Multifocal IOLs are designed to reduce spectacle dependance after cataract surgery. The diffractive trifocal lens(FineVision) uses a new concept of diffractive technology to provide three useful distance corrections.


BB Eye Foundation, Kolkata


Prospective case series comprising 54 eyes of 27 patients underwent clear corneal phacoemulsification under topical anaesthesia using standard surgical technique. Patients had bilateral implantation of FineVision trifocal IOLs. Uncorrected distance visual acuity, corrected distance visual acuity (CDVA) and manifest refraction were measured 1 month and 6 month postoperatively . Defocus curves were assessed under photopic and mesopic conditions over a range of +1.50 to -4.00 diopters(D) in 0.50 D Steps. Contrast sensitivity function was assessed under photopic conditions.


The mean monocular CDVA was 0.08 logMAR ±0.08(SD) and the mean binocular CDVA 0.06 ± 0.08logMAR. Defocus curve testing showed and extended range of clear vision from + 1.00 to -2.50 D defocus, with a significant difference in acuity between photopic conditions and mesopic conditions at -1.50 D defocus only. Photopic contrast sensitivity was significantly better binocularly than monocularly at all spatial frequencies.


The trifocal FineVision IOL is able to restore good visual acuity for distance, near and intermediate .Good agreement between theoretical and achieved outcome improving intermediate vision with a specific foci at 63 cm and not imparing near and far vision while providing intermediate vision. It also favours distance vision in mesopic conditions and reduces night vision problems, halos and glare.
