Until recently, cataract surgeons would rely on pre-surgery measurements and conduct a whole host of pre-op tests in order to figure out which intraocular lens (IOL) to prescribe to their patients. Now, there is a new type of lens that helps physicians optimize your vision once the lens has been placed inside your eye and after cataract surgery.
These are called a light adjustable lens. With it, there’s the ability to tailor specific measurements to your eye. Today, we’re going to discuss this new lens a bit with you and help determine whether or not you think it might be a good fit. Let’s jump right in!
How they work
Light Adjustable Lenses are made out of a photosensitive material that changes shape and the overall power of your lens via light treatments that can be administered by your cataract surgeon. Basically – you get your lens and depending on your needs you can receive treatments from your doctor that can adjust the lens to your needs.These treatments are both painless and non-invasive.
The benefits
Patients have reported a number of benefits since receiving their lenses, but perhaps the best one being 20/20 vision within 6 months of surgery – and achieved it faster than had they gone with glasses or your standard-issue monofocal IOL.
Additionally, the light treatments allow patients to almost preview what their vision will look like or view possible outcomes based on their needs. Doctors can adjust the lens to the exact shape of your eye to achieve the best possible vision.
Drawbacks
Like anything, Light Adjustable IOL’s do have some drawbacks as well. One of the more significant ones will be that after surgery – you’re going to have to wear blue blocker/UV protective glasses during all waking hours from implantation all the way until your final light treatment is done. This is important as failing to do so could significantly damage the lens.
The second and perhaps biggest issue is cost. Most health insurers will cover the cost of cataract surgery and most IOL’s – particularly monofocal IOL’s. An increasing number of insurers are covering Light Adjustable IOL’s but not nearly as many do and many patients have to pay out of pocket. What’s more – while the surgery may be covered, it’s not a sure-fire bet that adjusting the LAL after surgery is covered. So make sure you call your provider to get a more complete picture. While Light Adjustable lenses are great – they can be expensive.
Who’s the right kind of candidate?
Most people should be a good fit for this type of surgery – but there are some notable exceptions. If you have significant pre-existing macular disease, sensitivity to UV light, Uncontrollable eye movements or a history of herpes or shingles – you most likely will NOT be a candidate. To find out – simply schedule an appointment with your doctor.
