Purpose:
To evaluate the refractive and visual outcome after bilateral toric intraocular lens implantation and assess the impact on patients' health-related Quality of Life (QoL)
Setting:
2nd Department of Ophthalmology, Aristotle University of Thessaloniki, Papageorgiou General Hospital, Thessaloniki, Greece
Methods:
In a controlled case series study 34 eyes of 17 patients (9 female, mean age = 71.9 ± 8.4 years) were enrolled. All patients underwent a bilateral toric intraocular lens (IOL) implantation (Acrysof Toric, Alcon inc.) after uneventful cataract surgery performed by the same experienced surgeon. Keratometry values, best corrected (BCVA) and uncorrected (UCVA) distance visual acuity, best corrected near visual acuity (BCNVA) and manifest refractive spherical equivalent (MRSE) were measured at baseline and 3 months postoperatively. Toric IOL alignment error was evaluated at 3-months follow-up by means of electronic software using slit lamp photography. The 25-question version of the National Eye Institute Visual Functioning Questionnaire (NEI VFQ-25) was used to evaluate the postoperative patientsÂ’ visual quality and respective QoL.
Results:
BCVA as mean (±SD) improved from 0.31 (± 0.19) preoperatively to 1.02 (± 0.11) postoperatively (p<0.0001) while UCVA and BCNVA was assessed 0.77 (± 0.14) and J1 in all eyes respectively at the postoperative follow-up. Toric IOL alignment error was found less than 8 degrees in 31 out of 34 eyes (91.18%).No statistical difference was observed between pre-and post-operative corneal astigmatism (p = 0.819).The residual refractive cylinder was 0.55 ± 0.27 and postoperative MRSE -0.39 ± 0.13. The mean overall VFQ-25 score was 92.01, yielding a mean general health score of 58.92, while the mean general vision score was 81.07 (p<0.001).
Conclusions:
Bilateral toric IOL implantation proves to be an effective, viable and highly predictable method of managing corneal astigmatism, yielding high visual quality results. Careful patient selection, accurate keratometry and precise alignment of the cylindrical axes are some of the factors to be considered for a superior outcome. FINANCIAL DISCLOSURE?: No
