Relief of symptomatic pseudo-polycoria due to iris biopsy using a daily contact lens

Purpose: To report a case of pseudo-polycoria from iris biopsy managed by a daily disposable prosthetic colored hydrogel lens.

Observations: A 55-year-old- Caucasian female presented with complaints of photophobia in her right eye, that was exacerbated when going from a dark to light environment. Her past ocular history included a diagnosis by another outside physician of presumed multifocal iris melanoma in the right eye, followed by an iris biopsy performed one month later. Upon presentation to our clinic two months later, best corrected visual acuity was 20/20- in the right eye and 20/25 in the left eye. Slit lamp exam of the right eye revealed iris abnormalities, full-thickness biopsy defects at 2, 3 and 6 o'clock and a 0.8 × 0.7mm area of iris hyperpigmentation at 8 o'clock (Fig A,B,C, and D). The patient was provided with three non-surgical options to manage her symptoms: a commercially available soft daily replacement printed prosthetic hydrogel lens, a commercially available soft monthly replacement silicone printed prosthetic hydrogel lens, or a custom soft yearly replacement prosthetic hydrogel lens with dark inlay. The soft daily printed prosthetic hydrogel lens was chosen because of its ease in hygiene regimen and did not limit peripheral vision as the yearly dark inlay lens would.

Results: The patient now wears Alcon Dailies® Color, Base curvature 8.6, Diameter 13.8, color mystic green in the right eye and her symptoms of photophobia have been resolved (Figure F).

Conclusion: There are limited options to manage photophobia in patients with polycoria or pseudo-polycoria. Surgical intervention is dictated by how many quadrants of iris are involved and therefore how symptomatic a patient may be. A less invasive alternative to surgical intervention is the use of a contact lens. In this case, traditional hand painted or printed yearly or monthly replacement hydrogel contact lenses were not used. Instead, a daily disposable hydrogel was successfully fit, highlighting that there is often a simple solution to a seemingly complicated issue.
