Imagine an implant that can be fine-tuned after cataract surgery. An intraocular lens that can be precisely adjusted to your refractive needs. The Light Adjustable Lens is the breakthrough technology patients and surgeons have been demanding for years. A 90 second in-office “tune-up” eliminates astigmatism and customizes the lens to a perfect focus. This implant is ideal for post-LASIK patients, those who prefer monovision, and individuals who want the sharpest possible vision.
The specialized silicone of this implant can be modified using medical grade Ultraviolet (UV) light. Any deviation from target can be corrected after the eye has healed. Furthermore, you can test drive the refractive results and choose the endpoint that satisfies your visual needs.
Our RxSight LDD (light delivery device), shown below, resembles a standard office slit-lamp. It is computer driven and comfortably adjusts the Light Adjustable Lens to your specifications.
Our best pre-operative intraocular lens power calculation techniques are woefully inadequate. The graphic below, from an award winning paper, shows deviation from the ideal implant power using scattered error values. The innermost sphere encloses calculations whose power is off by less than 0.5 diopters. Greater than 15% of cases are greater than 0.5 diopters from optimal.
The graphic below shows 1000 patient calculations and their resulting deviation from optimal. Nearly 5% of patients are more than 1.0 diopters from ideal. The Light Adjustable Lens allows all patients to be enhanced and the scatter to be dramatically tightened and their refractive errors reduced. The RxSight Light Adjustable Lens should correct all patients to +/- 0.25 diopters from target. Furthermore, this technology eliminates errors from residual astigmatism.
While normal eyes generate a scatterplot like the one shown above, patients with a more complex cornea (LASIK, dry eye, longstanding contact lens wear, and irregular astigmatism) have even less predictability. Because the Light Adjustable Lens can minimize these errors, it is ideal for these special cases.
