We’ve got to get it right for these lenses to perform correctlyIn a prospective non-randomised study involving 66 eyes of 35 patients, Dr Lawless implanted non-toric PanOptix IOLs in 28 cataract patients and 38 refractive lens exchange patients. Mean preoperative spherical equivalent was +1.31D ±1.27 ranging from -1.75D to +4.00D, with sphere ranging from -1.50D to +4.00D, and cylinder from -1.50D to 0.00D. Mean follow-up was 4.3 weeks ± 1.4 weeks, ranging from two to nine weeks. Just over three-quarters of eyes were within 0.25D of target spherical equivalent and all within 0.5D, Dr Lawless reported. Mean post-op uncorrected distance visual acuity was 0.04 ±0.12 logMAR, or nearly 20/20, exceeding the pre-op corrected mean of 0.09 ±0.12, or about 20/25. Applying a 30-question validated survey of visual symptoms (McAlinden, IOVS 2010) to 10 patients, Dr Lawless found glare and halo symptoms were much higher than previous reports for spectacle-corrected monofocal IOL recipients at three months’ follow-up, and similar to those reported for previous multifocal IOLs. Nonetheless, Dr Lawless sees the PanOptix IOL as a viable choice for patients seeking spectacle independence, though careful patient selection and surgery are essential. “We’ve got to get it right for these lenses to perform correctly,” he said.
