Background.
The vision with diffractive toric multifocal intraocular lenses after cataract surgery in long eyes has not been studied previously.
Objectives.
To report visual performance after bilateral implantation of a diffractive toric multifocal intraocular lens in high myopes.
Methods.
Prospective, observational case series to include patients with axial length of ≥26 mm and corneal astigmatism of >1 dioptre who underwent bilateral AT LISA 909M implantation.
Postoperative examinations included photopic and mesopic distance, intermediate, and near visual acuity; photopic contrast sensitivity; visual symptoms (0–5); satisfaction (1–5); and spectacle independence rate.
Results.
Twenty-eight eyes (14 patients) were included.
Postoperatively, mean photopic monocular uncorrected distance, intermediate, and near visual acuities (logMAR) were 0.12 ± 0.20 (standard deviation), 0.24 ± 0.16 , and 0.29 ± 0.21 , respectively.
Corresponding binocular values were - 0.01 ± 0.14 , 0.13 ± 0.12 , and 0.20 ± 0.19 , respectively.
One eye (4%) had one-line loss in vision.
Under mesopic condition, intermediate vision and near vision decreased significantly (all P ≤ 0.001 ).
Contrast sensitivity at all spatial frequencies did not improve significantly under binocular condition (all P > 0 .
05 ).
Median scores for halos, night glare, starbursts, and satisfaction were 0.50, 0.00, 0.00, and 4.25, respectively.
Ten patients (71%) reported complete spectacle independence.
Conclusions.
Bilateral implantation of the intraocular lens in high myopes appeared to be safe and achieved good visual performance and high satisfaction.
