As Intra-ocular Lens (IOL) technologies continue to improve and progress in their capability to deliver sharp vision at a wide range of distances, current cataract surgical treatment has basically ended up being refractive lens surgery.
As each iteration and generation of new IOL technology continues to provide much better and more consistent outcomes, cataract surgeons are significantly implanting more than just the standard mono-focal lens, rather there is a bent towards multi-focal and other premium lenses.
Nonetheless, the approval rating for changing a lens simply for refractive objectives, a procedure described as refractive lens exchange (RLE), stays questionable.
A previous commonly held misconception was that ophthalmologists do not have LASIK carried out on their own eyes, which was resolved by 2 research studies in 2014 and 2015.
Outcomes of the initial study, showed that physicians that had had LASIK had a 95.3% satisfaction rate with their outcomes, and also the results from the second research study, showed that refractive surgeons are 4 times more probable than the general population to undertake laser vision improvement.
Considering those outcomes, a couple of doctors decided to utilize the very same technique to test effects of RLE by asking surgeons about their very own experiences with going through the procedure.
Research study design
The researchers planned a potential, randomized-survey research study to figure out the prevalence of RLE amongst active refractive surgeons, their recommendations to family as well as good friends to undertake the procedure, and the satisfaction rates among the eye surgeons who undertook the procedure.
500 ophthalmologists were picked randomly to get the 29-question study from amongst 2441 eye doctors that had actually used a particular software to plan refractive surgeries; specifically, they were asked about their personal experience with refractive surgical procedures.
The primary purpose of the research study was to test the prevalence of RLE among refractive eye doctors, however the research additionally looked at whether those surgeons had advised RLE to family and family members, and also whether those family members had undergone RLE.
The study additionally sought to define the mindsets and satisfaction rates among refractive specialists that went through RLE.
The premise was that the prevalence rate of RLE amongst refractive eye doctors might suggest the prospective penetration of the treatment in the marketplace gradually.
Preliminary results were based off a 64.3% survey respopnse rate.
Ninety-nine percent of the responders considered themselves refractive surgeons as well as 34% had undertaken a laser vision correction themselves.
Virtually 50% of those who went through laser vision improvement were in their 30s, 30% in their 40s, and 22% in their 20s at the time of surgery.
Of the survey responders, 8.5% reported having actually undergone a lens procedure for cataract (90%) and emmetropic presbyopia (10%).
An interesting finding was that 24% of the responders stated they had prepared for undergoing RLE for presbyopia; those that would not undertake the treatment were closer to the age of cataract surgery, and wished to wait for improved intraocular lens technologies, were worried about potential issues, would certainly not be able to tolerate multifocality, or reported the existence of a pre-existing ocular factor that would certainly hinder RLE.
Based off the first responses, the main study conclusions are that of the majority of refractive eye doctors who are carrying out RLE, almost one-third have actually recommended RLE to close relatives, and practically a 5th have family members who have actually gone through RLE.
