Every year, surgeons come up with innovative technologies to make the process of cataract
surgery easier, precise, and safer. One of the major steps in cataract surgery is the implantation
of an intraocular lens implant or IOL in place of the natural lens of the eye. An IOL must be
designed with specific attention to the health of the individual's eye. For instance, a person who
has presbyopia needs IOLs that are specifically meant for correcting presbyopia.
In addition, surgeons are always faced with the dilemma of calculating just the right power for
every IOL. A perfectly calibrated IOL results in quality of vision.
Calculating the power of the IOL is tricky in that it involves taking very precise measures. There
are several theoretical formulas and techniques often employed by surgeons and
ophthalmologists for the purpose. These equations and formulas are very generic in their
approach and do not cater to the individual needs of the patient.
This is why surgeons have now resorted to the use of artificial intelligence for IOL power
calculations.
How is AI calculation of IOL power approached?
One of the first steps in the use of AI for lens implant power calculations is to train AI systems on how to
approach such calculations. This is where big data comes into play. The AI systems are trained
with inputs of real data that contain the important variables used in the calculation of the IOL
power. In training cases, the output for each input to the system is already known.
The AI systems use the given data and compare it with existing data sets to predict a possible
power for the IOL.
The AI method is still being tested and cannot be completely used to accurately predict the IOL
power for individuals. Given the circumstances however, the AI approach offers a fresh
perspective and is a promising aspect in the field of cataract surgery.
AI predictions are not fully dependable, especially since a lot of data that is specific to certain
individuals is still sparse. This is why scientists, engineers and ophthalmologists are working
together to bring together the data that will make IOL calculations even more precise.
An advantage of using AI is that variables can be easily input into the system and corrections are
made without any risks once all the necessary details are known.
In fact, certain AI systems are being used reliably by incorporating certain formulas that increase
the accuracy of the results to a certain level.
Once the AI technique is perfected, it will be a revolutionary breakthrough in the field of
ophthalmology and patients can expect better quality in their vision.
