To evaluate the postoperative outcome of Toric inter ocular lens (IOL) inplanted cataract surgery between skilled surgion and trainee.
We analized 75 eyes of 69 patients with preexisting astigmatism between 0.75 diopter (D) to 2.5D who were undergoing cataract surgery using AcrySof Toric IOL (Alcon Laboratories Inc, Fort Worth, Texas, USA ). 54eyes were operated by a skilled surgeon (14 years of practice, cataract surgery experience of 3000eyes, 197 of which are Toric IOLs ) and 21eyes were operated by a trainee (3years of practice, cataract surgery experience of 98eyes, with no previous Toric IOL inplantation experience ) initial 6 o’clock mark placed at sitting position before start of the surgery and 2.2mm or 2.4mm corneal incision placed at 12 o’clock. The postoperative outcome ( Logarithm of the minimum angle of resolution uncorrected visual acuity (logMAR UCVA), postoperative astigmatism(D), and axis rotation of the IOL in degrees(°)) were measured at 3 month postoperatively. To investigate the changes in corneal astigmatic component, we converted pre- and postoperative astigmatism into a non-signed Astigmatic Power Vector (APV), which represents the magnitude of the astigmatic error, using Fourier analysis.
There was no statistical difference in mean postoperative logMAR UCVA between trainee and a skilled surgeon (0.19 and 0.13 respectively, p=0.60). Also, there were no statistical differences in postoperative astigmatism (0.57D, 0.61D p=0.49) and IOL axis rotation (6.23°, 5.93°p=0.73) between two groups.
In using Toric IOLs, trainees, under appropriate guidance, could achieve equivalent postoperative outcome against that of a skilled surgeon.
