Another success story in the books for a patients with keratoconus!

This was the patient’s first time wearing scleral lenses and she was ecstatic about her vision with the lenses. However, some raised tissue on her sclera (called a pinguecula) was making scleral lens wear pretty uncomfortable. She had symptoms of stinging and blurred vision after a few hours of wear time.

📸 1/6: In this photo, a circular area of white tissue surrounded by blood vessels can be seen. This is due to the lens compressing on the pinguecula.

📸 2/6: In blue light, an air bubble can be seen underneath the edge of the lens. This gap between the contact lens and her eye can allow debris to enter the contact lens, making vision blurry. And over time, this gap can cause dryness, which isn’t an issue we would want to contribute to.

📸 3/6: This was the fun part! Our Pentacam Software mapped out all the elevations of this patient’s sclera. The burgundy areas indicated by the black lines were where the locations of those raised tissues. It turns out, she had 2 of them!

📸 4/6: Ok, another fun part was designing a lens to vault over both of those pingueculas. We went with a lens from BostonSight due to their ability to incorporate vaulting in 2 areas of the lens. (Most other lens designs can only accommodate 1)

📸 5/6: With the new lens design, the gap that was there previously is no longer present! 🥳

📸 6/6: Lastly, the compression of the blood vessels has improved considerably.

This patient has been wearing their lenses for the last year with no issues. And we are excited to see her again for her yearly fitting!

After seeing several eye care providers and being unsuccessful at finding glasses to relieve nighttime glare symptoms, this patient came to see us for some alternate solutions.

During his visit, we conducted diagnostic testing with our Pentacam topographer, which revealed microscopic irregularities on his corneas.

These irregularities cause light to scatter as soon as it passes through the cornea, explaining the glare issues he was experiencing. While glasses alleviate a percentage of the glare, they do not provide 100% relief.

We fitted this patient with a rigid contact lens that masked all corneal irregularities, thus eliminating all glare symptoms.

The patient already had 20/20 vision, but he went from seeing starbursts and halos when looking at lights to seeing one single point of light. He was extremely thankful and relieved to drive comfortably again at night!

Hello everyone! I am entirely overdue for an intro, so here it is!

My name is Lay Nim, I’m a board certified optometrist and I specialize in all things related to the cornea and contact lenses. I’m also the owner of Precision Vision Institute, my practice that I started cold in July of 2020. Yes, smack dab in the middle of a pandemic! (And yes, “THE” year of all years to open an optometry practice, because…20/20 🤪)

After a wild 18 months of this roller coaster ride, and finally getting the hang of things. I’m excited to start sharing stories of all the patients I’ve had the opportunity to help while running a contact lens focused optometry practice.

Follow along if you’d like to learn more about the cornea and contact lenses and see why I’m grateful to be doing what I do everyday!
