Purpose To evaluate the clinical results after implantation of a spherotoric intraocular lens (IOL) using the bag-in-the-lens (BIL) technique. Setting Antwerp University Hospital, Department of Ophthalmology, Antwerp, Belgium. Design Evidence-based manuscript. Methods Consecutive eyes with cataract and corneal astigmatism had implantation of a spherotoric BIL intraocular lens (IOL). The IOL was centered based on the patients pupillary entrance using Purkinje reflexes of the surgical microscope light. Results The study enrolled 52 eyes of 35 patients (23 women) with corneal astigmatism ranging from 0.90 to 6.19 diopters (D). The toric power was between 1.00 D and 8.00 D. One-third of eyes had an additional ocular comorbidity (including amblyopia) that could influence the clinical outcomes; 5.2% had an irregular astigmatism up to 15 degrees. Twelve eyes had high myopia (axial length [AL] >26 mm) and 5 eyes, high hyperopia (AL <21 mm). The mean preoperative corrected distance visual acuity was 0.58 ± 0.25 (SD). Postoperatively, the uncorrected distance visual acuity (UDVA) was 0.5 or better in 92% of eyes, the mean UDVA was 0.85 ± 0.21 D, the mean magnitude of error was 0.05 ± 0.49 D, and the mean angle of error was 0.29 ± 0.89 degree. Astigmatism correction was successful in 82% of eyes. Conclusion Spherotoric BIL IOL implantation yielded outcomes similar to those with other spherotoric IOLs, even in eyes with ocular comorbidity or irregular astigmatism up to 15 degrees.
