There are many innovations currently emerging in the field of eye surgery. However, Light Adjustable Lenses (LALs) stand out. It provides a certain degree of precision that was previously unattainable.
Have you ever wondered whether vision correction could be customized after surgery, as opposed to using pre-operative measurements alone? This technology is a significant breakthrough. And as more clinics in Europe now provide state-of-the-art refractive solutions, including those pioneered by EuroEyes, the influence of LALs is now taking a new dimension.
Learning about Light Adjustable Lenses
Light Adjustable Lenses do not operate like conventional intra-ocular lenses (IOLs). Rather than being permanently printed on the day when they are implanted, these lenses are fabricated in a special photosensitive material. The lens is adjustable for some time after it is put in your eye in a cataract or lens-replacement surgery.
This is what makes the technology so revolutionary. It is adjustable. Your vision can be fine-tuned after the eye has healed. This is when your refractive outcome is much more stable.
Historically, surgeons were guided by complex formulas to decide the ideal lens power prior to surgery. However, even with the most recent and advanced equipment, the eye does not necessarily act in the predicted manner. Much of this guesswork is eliminated by LALs.
The adjustment process: How it works
When your eye is healed, you go back to have a series of light treatments. These are painless procedures carried out on the lens whereby controlled ultraviolet (UV) light is induced on the lens to alter the shape and refractive strength. The treatment progressively focuses the lens a little bit nearer to your desired image and gradually brings your vision nearer to your desired outcome.
You are actively a participant in the process: you explain how particular you can see at various distances, how comfortable it is to you, and how it affects daily activities. Your surgeon further adjusts based on this feedback and accurate measurements. This is a personalized way to correct your vision.
Once you and your surgeon are satisfied that the outcome is just right, the lens is fixed permanently by the final light treatment, which sets its form permanently. Subsequently, the refractive power is fixed.
Why this technology matters
The customization of vision post-surgery eliminates surprises and increases accuracy. In your case, this will equate to increasing chances of achieving your visual objectives. It may be to have sharp distance perception, a better near focus, or a balance between the two.
Light Adjustable Lenses are particularly useful when you have had LASIK, PRK, or SMILE before, since it is harder to calculate lenses after other refractive surgeries have been done. In the case of LALs, the first result is not always ideal, and it can be modified.
Wrapping up
Light Adjustable Lenses provide an opportunity in medicine that few have had: the opportunity to adjust the result after the operation. To most, that translates to having a clearer, sharper, and more personalized vision.
