Abstract Details

Purpose:

Trifocal intraocular lenses (IOLS) have been shown to provide patients with optical independence across a full range of activities. Optimising refractive outcomes remains essential to maximizing the visual capabilities of the lenses therefore minimizing postoperative refractive astigmatism is key to meeting patient expectations. Utilizing a toric IOL platform to achieve refractive endpoints may further assist these overarching goals.

Setting:

Patients undergoing cataract and IOL insertion with the Panoptix Toric IOL at a single private ophthalmic surgery centre

Methods:

10 patients (20 eyes) undergoing toric IOL insertion were reviewed at least 6 months postoperatively. Routine examination included visual acuity, refraction, Defocus curve and quality of vision questionnaire (QUIVID). Astigmatic vector analysis was completed in addition to standard refractive parameters. Patients underwent a process of tear film optimization prior to biometry if warranted through preoperative subjective and objective dry eye evaluation. Patient self-reported outcomes (non-prompted) on daily activities were documented in clinical case notes.

Results:

Mean age of patients was 67.5 years. Mean keratometry and preoperative corneal cylinder were 42.7±1.24D and 0.83±0.74D respectively requiring T2 to T6 IOLs at surgery. Mean Spherical equivalent was 0.06±0.16D at 1 month. Ninety-five percent of eyes achieved sphere and cylinder values ≤ 0.5D following surgery. Eighty percent of eyes achieved a combination of 6/6 and N6 or better for distance, intermediate and near vision. The majority of subjects were not at all bothered by starbursts, halos, glare or other phenomena however 2 (20%) patients described the presence of severe glare following surgery.

Conclusions:

Refractive and visual results achieved with the Panoptix trifocal toric IOL match best-practice published outcomes. Although a small number of patients continued to describe photic phenomena at greater than 6 months post-surgery, the severity and impact of these phenomena appeared to rarely impact daily activities. The concurrent ability to treat corneal astigmatism may further benefit patients seeking optical independence following lens-based procedures.
