Research Article: Clinical performance of the pseudo-non diffracting beam Toric EDOF intraocular lens: visual function, rotational stability, and quality of life
Abstract:
To evaluate visual acuity, refractive outcomes, rotational stability, and patient-reported satisfaction 3?months after bilateral implantation of the Lucidis Toric extended-depth-of-focus (EDOF) intraocular lens in cataract patients with 1.00–3.00 D of regular corneal astigmatism.
Prospective, single-arm study of 25 patients (50 eyes) undergoing phacoemulsification with bilateral Lucidis Toric IOL implantation. The primary endpoint was binocular uncorrected distance visual acuity (UDVA) at 3?months. Secondary endpoints included monocular/binocular UDVA, distance-corrected VA (DCVA) at 4?m; intermediate (80?cm, 66?cm) and near (40?cm) uncorrected and distance-corrected acuities; defocus curve; residual spherical equivalent (SE) and cylinder; IOL rotation; optical quality (MTF cutoff, Strehl ratio, HOA RMS); contrast sensitivity; halometry; and NEI-RQL-42. Paired t -tests or Mann–Whitney tests compared pre-/postoperative values.
At 3?months, the mean postoperative spherical equivalent was 0.17?±?0.52 D (median 0.00 D; range ?0.75 to +0.75 D) and the mean refractive cylinder was 0.04?±?0.32 D (median 0.00 D; range ?0.50 to +0.50 D). Median IOL rotation was 2.1?±?2.3 degrees, with no eyes requiring repositioning. Mean binocular UDVA, UI80VA, UI66VA and UNVA were ?0.01?±?0.1, 0.08?±?0.24, 0.04?±?0.1, and 0.01?±?0.14 logMAR, respectively. There were no statistically significant differences between uncorrected and distance-corrected visual acuities at any distance. The binocular defocus curve showed visual acuity better than 0.1 logMAR from +0.50 D to ?3.00 D. NEI-RQL-42 scores indicated high patient satisfaction, particularly in clarity of vision, far, near vision, activity limitations, and glare domains.
Bilateral Lucidis Toric EDOF IOL implantation delivers stable rotational performance, broad-range uncorrected vision, and high spectacle independence in astigmatic cataract patients. Future randomised, head-to-head trials with longer follow-up are warranted.
Introduction:
Phacoemulsification with intraocular lens (IOL) implantation is the most commonly performed ophthalmic procedure worldwide; it restores vision by replacing the opacified crystalline lens with an artificial optic. Conventional monofocal IOLs deliver high-quality vision at a single focal point, but patients typically require spectacles for either near or distance tasks ( 1 , 2 ). As life expectancies rise and visual demands broaden, there is growing interest in premium IOLs that extend uncorrected,…
