Webinar: Eaglet Eye - Going Deep and Wide on Specialty Contact Lens Fitting (May 29, 2024)

Featured on Eaglet Eye

In these two webinars, Dr. Langis Michaud, Dr. Sheila Morrison and Dr. Aaron Wolf share with us their in-depth experience using corneo-scleral 3D measurements from the Eye Surface Profiler to take specialty lens fitting deeper and wider than was possible before.

1. In the first webinar, we delve deeper into scleral and hybrid lenses.

2. In the second webinar, we widen our focus to cover the other specialty lens modalities, including OrthoK, GP, and custom soft lenses.

"Going Deep and Wide on Specialty Contact Lens Fitting (I)" 

Summary: Explores the use of corneo-scleral 3D measurements (using the Eaglet Eye Surface Profiler) to improve fitting accuracy for scleral and hybrid lenses. Key case studies highlight how this technology streamlines the process, reduces chair time, and enhances patient comfort.

Case Studies Covered:

• Post-Lasik Ectasia (05:35): Dr. Michaud demonstrates fitting scleral lenses for a patient with irregular cornea profiles following refractive surgery, emphasizing the need for customized fits to prevent misalignment and midday fogging.

• High Order Aberrations (15:25): Dr. Morrison discusses correcting high-order aberrations (HOA) using BostonSight Scleral Smart 360 lenses to improve visual acuity in patients with clear but distorted corneas.

• Difficult Case Study (28:19): Dr. Michaud presents a challenging case involving a corneal graft, showcasing how precise mapping overcomes high irregularities caused by surgical sutures.

• Hybrid Lenses (40:52): Dr. Michaud shows that for certain patients, specifically a young trauma victim, hybrid lenses may be a better option when handling scleral lenses is too difficult, despite significant surface irregularities.

• Q&A Session (54:28): The experts discuss criteria for moving from corneal lenses to sclerals, interpreting topographical metrics (like kmax), and the benefits of mastering multiple lens designs using advanced mapping tools.

This webinar, "Going Deep and Wide on Specialty Contact Lens Fitting - Part 2," focuses on specialized lens modalities beyond scleral lenses, featuring insights from Dr. Langis Michaud, Dr. Sheila Morrison, and Dr. Aaron Wolf. The session highlights the use of the Eaglet Eye Surface Profiler (ESP) to enhance efficiency and success in fitting corneal GPS, OrthoK, and custom soft lenses.

Key Case Studies and Topics:

• OrthoK Lens - Monovision Myopia Translimbal: (4:48) Dr. Wolf discusses fitting a 47-year-old patient with a translimbal OrthoK design, utilizing the ESP to map the entire corneal surface and manage scotopic pupil size for better nighttime vision.

• Corneal GP Lens - Post-Lasik: (31:32) Dr. Morrison shares a case fitting a corneal GP lens on a post-LASIK cornea, emphasizing the use of diagnostic fitting techniques.

• OrthoK Lens - Hyperopic Patient: (36:19) Dr. Wolf covers hyperopic OrthoK for a 63-year-old patient, explaining the difference in mapping (warmer colors for steepening) compared to myopic OrthoK.

• Custom Soft Lens - 2 Curves are Better than 1: (55:36) Dr. Morrison demonstrates fitting a custom soft lens using profilometry data to create a more stable, comfortable fit.

• Corneal GP Lens - Corneal to Corneal: (1:01:35) Dr. Morrison briefly discusses transitioning a patient from one corneal GP lens to another using new data.

• Key Takeaways: The ESP is highlighted as a multimodal instrument that reduces guesswork by providing accurate 3D surface data, which is essential for customized lens algorithms and improved patient outcomes.
