"Light Adjustable Lens: Evidence, Patient Selection & Practical Guidance" presented by Dr. Tanner J. Ferguson

Learning Objectives: 

1. Describe the design and mechanism of the light adjustable lens. This includes how UV light from the Light Delivery Device changes lens power, the adjustment range, and the sequence of adjustments and lock-ins.
2. Identify appropriate candidates for the LAL, including eyes with prior refractive surgery and concomitant pathology. Understand and recognize features that limit outcomes, such as elevated higher-order aberrations, irregular Placido imaging, multiple prior laser vision corrections, and poor dilation.
3. Apply recent clinical evidence and practical pearls to counsel patients and optimize outcomes. The evidence is the FDA Post-Approval Study vs toric IOLs, the Phase IV registry, and other recently published data. The pearls cover tear film, timing of adjustments, and targeting of LAL

Pre-Presentation Questions: 

1. What is the labeled adjustment range of the LAL?
   1. ±1.00 D sphere; up to 1.00 D cylinder
   2. −2.00 to +2.00 D sphere; up to 2.00 D cylinder
   3. ±4.00 D sphere; up to 4.00 D cylinder
   4. Sphere only; astigmatism requires a toric LAL
2. Which best describes the standard adjustment process?
   1. Unlimited adjustments with no lock-in required
   2. Up to 3 adjustments, followed by 2 separate lock-in treatments
   3. One adjustment and one lock-in at the 1-week visit
   4. Adjustments begin on postoperative day 1
3. Which of the following patients is not an ideal candidate for the LAL?
   1. A 62-year-old with a long history of happy monovision contact lens wear
   2. A 66-year-old with prior myopic LASIK, a well-centered ablation, and regular Placido imaging
   3. A 68-year-old with reduced BCVA from corneal irregularity who relies on a scleral contact lens for their best vision
   4. A 70-year-old who values crisp distance vision and is averse to the risk of glare and halos
