Purpose To study the visual results and tolerance of a Zeiss CT Lucia 601P intraocular lens (IOL) implanted in the sulcus after complicated cataract surgery or during IOL exchange for clouded IOL. Methods In total, 64 patients who underwent sulcus implantation were recalled to the hospital to undergo subjective and objective refraction, best corrected visual acuity measurement, tonometry, optical coherence tomography, laser flare photometry, biometry, and wavefront aberrometry. Results In spite of a large variation in preoperative refraction, the target refraction was obtained within 1.5 diopters in approximately 97% of patients and within 0.5 diopter in 53% of patients. Average BCVA was high (Snellen 0.86) and related to concomitant (mostly retinal) pathologies in eyes with poorer visual performance. Wavefront aberrometry showed no evidence of IOL tilting or decentration after long-term implantation in the sulcus. Tonometry was not different from the fellow eye of the patient ( p  > 0.5). In 53 patients with bilateral pseudophakia, the laser flare photometry was not significantly different from the fellow eye ( p  < 0.05). Conclusion This study demonstrates that this single-piece angulated foldable acrylic IOL can be considered for implantation in the sulcus. The visual results are favorable, and the IOL can be well-positioned and tolerated in the sulcus. Moreover, there were no safety issues found since there was no evidence of elevated IOP or chronic uveitis.
