Abstract Details

Purpose:

To analyse the refractive results and postoperative complications after cataract surgery through implantation of AcrySof® toric intraocular lens in 23 patients.

Setting:

We analized 35 eyes of 23 patients from the ophthalmology department of Virgen del Rocío Hospital in Seville, Spain that were diagnosed with cataract and regular corneal astigmatism. The mean age at diagnosis was 57,52 years.

Methods:

35 eyes diagnosed with cataract and regular corneal astigmatism. Mean age:57,52 years. History of LASIK in one eye, implantation of intrastromal segments for keratoconus in another, four eyes were amblyopic, two had colour vision defect, two had a myopic choroidosis and one eye had corneal scarring. Preoperative CDVA was 0.38 on average and average IOP: 15.5 mmHg. Average preoperative refractometry showed a sphere of +4.60 diopters in hyperopic group and -5.49 diopters in myopic; average astigmatism of -3.60 diopters. Preoperatively, corneal astigmatism and axial length was measured through an optical biometer (IOLMaster) to calculate the power of the IOL implant.

Results:

All eyes were operated by phacoemulsification and aspiration of cataract with posterior implantation of AcrySof® toric IOL. The postoperative IOP was 14.86 mmHg on average. Two months after surgery, uncorrected distance visual acuity (UDVA) improved to 0.8(decimal scale) on average and postoperative refractometry showed a sphere of +0.46 diopters on average in hyperopic and -0.61 diopter in myopic; average astigmatism was-0.64 diopters. As immediate postoperative complications noted IOL rotation in three eyes, which required reoperation. In 4 eyes Bioptics (PRK) was required due to residual refractive error. Dry eye syndrome, transient ocular hypertension and anterior uveitis,were also recorded and resolved without sequelae with medical treatment.

Conclusions:

The analysis of this series shows that the implantation of AcrySof® toric IOL is effective in correcting previous corneal astigmatism in cataract surgery and maintains good rotational stability in the long term. However, in some cases clinically relevant turnover in the immediate postoperative period may occur, which would require reoperation.
