Abstract Details


To evaluate the visual outcomes of pseudophakic patients who underwent supplementary toric intraocular lens (IOL) implantation to correct astigmatic refractive errors.


Two clinical centers, Lisbon, Portugal.


This retrospective case series included patients who were referred for implantation of a supplementary toric IOL (Sulcoflex Toric 653T, Rayner Intraocular Lenses Limited.) to correct residual astigmatic refractive errors after phacoemulsification. The postoperative refractive target was emmetropia. Uncorrected and corrected distance (UDVA and CDVA, respectively) visual acuities, spherical equivalent (SE) refraction, residual astigmatism, rotational stability, higher order aberrations (HOA) and photopic glare and no-glare contrast sensitivity (CSV-1000, VectorVision) were evaluated. Postoperative follow-up was at 1 day and at 1, 3, 6, 12, and 18 months.


10 eyes of 10 patients were included. 7 eyes with residual refractive error after phacoemulsification, 1 post-radial keratotomy, and 2 with post-LASIK corneal ectasia after corneal collagen crosslinking. The mean age was 56.42 ± 5.9 years (range 45 – 65 years). Mean follow-up was 6.71 ± 4.8 months (3 – 18 months). Mean pre-operative logMAR UDVA and CDVA were 1.00 ± 0.53 (1 – 0.22) and 0.20 ± 0.13 (0.4 – 0), respectively. Postoperatively, UDVA improved to 0.10 ± 0.12 (0.3 – -0.1) (p=.004) and CDVA to 0.07 ± 0.12 (0.3 – -0.1) (p=.021). Mean SE refraction decreased from -2.20 ± 3.26 diopters (D) (-7.00 – +0.875) pre-operatively to -0.30 ± 0.56 D (-1.00 – +0.75) (p=.183). Mean toric IOL axis rotation at 6 months follow-up was 3.0° ± 2.45° (0 – 6). Ocular aberrometry values decreased after surgery (average HOA RMS 0.63 ± 0.21 preoperatively vs. 0.48 ± 0.26 postoperatively; p=.008). Photopic contrast sensitivity improved slightly after surgery (p>.05 for all spatial frequencies).


The implantation of the Sulcoflex Toric IOL to correct astigmatism in pseudophakic patients provided excellent visual outcomes, predictability of refractive results, rotational stability and optical performance. The implantation of this IOL is a safe and efficient technique to correct pseudophakic cylindrical refractive errors and reduce spectacle dependence in these patients.
