Abstract Details

Purpose:

To assess visual acuity, astigmatic reduction and rotational stability of Rayner T-flex toric intraocular lenses (IOL) in a series of cataract and refractive surgery patients with corneal astigmatism.

Setting:

Charles University, Dept. Ophthalmology, Hradec Králové, Czech Republic

Methods:

This retrospective study included 44 eyes of 29 patients (mean age 54,7 ± 12,4 years / range 33 to 79) with mean pre-operative corneal astigmatism -2,08 ± 1,09 D (range -0,76 D to -5,72 D) in which Rayner T-flex toric IOL implantation was performed after phacoemulsification. Mean IOL cylinder power was 2,40 ± 1,44 D (range 1 D to 8,5 D). Patients were divided into 3 groups (target emmetropia, target mopia, patients with amblyopia). Uncorrected distance visual acuity (UDVA), best corrected distance visual acuity (CDVA), residual refractive sphere, residual refractive cylinder and rotational stability were measured three months after surgery.

Results:

Mean postoperative UDVA of patients who were planned to emmetropia (n = 22 eyes) was 0,04 ± 0,05 logMAR and mean CDVA was 0,02 ± 0,03 logMAR. Mean refractive postoperative sphere was 0,14 ± 0,54 D and mean refractive postoperative cylinder was -0,3 ± 0,58 D. The mean absolute IOL rotation 3 months after surgery was 4,05 ± 2,92 degrees. Rotation less then 10 degrees was noted in 94% of eyes an rotation less then 5 degrees was noted in 61%.

Conclusions:

Rayner T-flex toric IOL implantation is an effective and reliable option to correct corneal astigmatism in cataract and refractive surgery.
