Care Optometry, we have recently had the opportunity to fit a new patient with a scleral lens.
😎The patient’s past medical history included a deep corneal laceration, iris defect, lens extraction, and laser peripheral iridectomy, which had caused blindness in her left eye for 15 years.
👓Despite wearing glasses, her visual acuity in the left eye was limited to 20/400 due to a corneal scar.
👀Furthermore, she experienced chronic dry eye, including superficial punctate keratitis and limbal injections. However, following the scleral lens fitting, her vision improved substantially to 20/20-
☀️We are pleased to see her benefit from our care with specialty contact lenses. The scleral lens is functioning as intended, creating a smooth refractive surface over an irregular, scarred cornea. The tear reservoir (fluorescein layer) is key for both visual rehabilitation and ocular surface protection.
What’s visible in the video:
Dense corneal opacity (scar): The central-to-peripheral whitish area represents stromal scarring, which disrupts the normal clarity of the cornea and contributes to reduced vision.
Iris defect (sectoral): The darker, irregular area behind the cornea suggests a loss or distortion of iris tissue, which can lead to light scatter, glare, and decreased visual quality.
Fluorescein pattern: The greenish glow indicates the tear reservoir created by the scleral lens. This fluid layer vaults over the cornea, helping to mask surface irregularities from the scar, improve optical quality, and protect the ocular surface.
Conjunctival/scleral vessels: The dilated, tortuous vessel suggests pre-existing chronic surface inflammation and chronic irritation. The localized vascular change may also be due to chronic dry eye.
This patient will be carefully monitored during fitting and follow-up care to ensure the treatment will improve the overall ocular health.
