Abstract Details

Purpose:

To investigate the quality of this new extended range vision lens, including biometric accuracy, the visual performance, the need for glasses post operatively, and the induction of post operative photic phenomena’s, such as haloes and glare

Setting:

Eye & Laser Centre Gold Coast, Australia

Methods:

Forty subjects (80 eyes) were bilaterally implanted with the new TECNIS Symfony IOL, and retrospectively studied to investigate the quality of this new extended range vision lens. Mean age of subjects were 67.53years, 67.5% female and 32.5% male. Patients were routinely examined preoperatively to ensure safety for surgery. All patients underwent Pentacam topography, IOL Master biometry, and where appropriate or necessary, OCT of the disc and maculae, and visual field assessment. All patients were healthy with no eye or systemic disease of note.

Results:

100% subjects (n=40) achieved highly satisfactory uncorrected distance visual acuity (UDVA) of 1.0 or better, with 100% subjects not requiring the use of glasses for distance vision 4-6 months postoperatively. Intermediate visual acuity of 0.5 or better was achieved by 92.5% patients, 80% achieving >1.0 VA, 87.5% of all patients did not require glasses for intermediate use 4-6 months postoperatively. Near visual acuity of 0.5 or better was achieved by 100% patients with 77.5% achieving 1.0 or better. It was noted 37.5% patients did require reading glasses for near work only and 62.5% patients not requiring glasses for near tasks 4-6 months postoperatively. With respect to Photic Phenomena, the main effects noted were halos and starbursts, 2.5% and 2.5% respectively.

Conclusions:

We found this an extremely successful intra-ocular lens, for both the surgeon and patient satisfaction. Patient satisfaction questioning suggested that 97.5% of patients would choose the same lens again or recommend it to friends and family. The high success profile of this IOL suggests that this lens could be used as a default intra-ocular lens, as long as the potential for night time photic phenomena is explained as well as the possible need for occasional reading assistance in low light.
