Theres no need for further surgery or any other form of invasive treatment. As long as there are untreated macromers further adjustments to refine the corrections can be made by directing light to different areas of the lens. This polymerization creates a concentration gradient between the irradiated region and the rest of the optic. Dr. Maloney said that with this lens, the patient has routine cataract surgery, and several weeks postop, instead of prescribing spectacles, the surgeon exposes the LAL to a precise pattern of light that changes the shape of the lens to correct the residual refractive error. Lichtinger A, Sandstedt CA, Schwartz DM, Chayet AS, Correction of astigmatism after cataract surgery using the light adjustable lens: a 1-year follow-up pilot study. Prominent Tampa eye surgeon, Craig Berger, MD has just become one of a handful of Florida ophthalmologists to offer the new Light Adjustable Lens from RxSight.

With more lens elements inside the lens, fixed aperture lenses weigh considerably more than their variable aperture counterparts. The corneal astigmatism can change over time which might effect the permanence of the vision provided by the LAL. This lens is implanted similarly to the other lenses discussed. When light (365 nm wavelength UV light) is directed to a specific area of the lens, macromers in the path of the light get activated and attach to the ends of other macromers forming polymers. The 16 eyes implanted with the LAL showed no signs of corneal, anterior segment, or retina toxicity while the three eyes in the control group that received the highest irradiation dose had areas of focal retinal damage. Although I currently employ corneal topography and wavefront aberrometry, swept-source OCT biometry, multiple advanced formulae, intraoperative aberrometry, and digital intraoperative axis localization, an ophthalmologist right out of residency should achieve better refractive outcomes with an adjustable IOL than I currently do using all of these technologies for my toric monofocals, he said.

This makes the results more precise, and more importantly, leads to better vision outcomes after you have cataract surgery. In order to prevent uncontrolled polymerization of the silicone macromers with unpredictable changes in IOL power from incidental exposure to indoor or outdoor sources of UV light before the lock-in step, the protocol requires the patient to don UV protective glasses during all waking hours of the day right from the time of the surgery, all through the healing and light treatment process , till 24 hours after the final light treatment. Glasses may be removed while sleeping, and may also be temporarily taken off while applying eye drops and taking a shower as long as the patient is not exposed to direct sunlight. The projected light is circular in shape and has a very soft edge. The project was spearheaded by Danial Schwartz, M.D. On the other hand, the LAL is highly customizable since a patient's prescription is applied to the lens after surgery. Monovision can be created by adjusting the LAL to the desired amount of myopia, then the patient is given time to adjust to his monovision, which, in case the patient cannot adapt or is not happy, can be further modified or completely reversed with a second adjustment before the lock-in of the lens, something that can only be done with this technology.
