Lasik technology advancements minimise risks of regression - Ophthalmologists
Regression occurs when the eyes partially revert to their pre-surgery prescription, leading to worries that the money spent on surgery could be wasted.
SHAH ALAM - Despite the popularity of Lasik surgery as a quick and widespread method for correcting vision, there are common concerns and misconceptions about its potential for regression.
Regression occurs when the eyes partially revert to their pre-surgery prescription, leading to worries that the money spent on surgery could be wasted.
IKONIK Eye Specialist Centre ophthalmologist Datuk Prof Dr Muhaya Mohamad said advancements in technology have significantly reduced the risk of regression.
“While the fear of regression persists, out of 5,000 to 6,000 patients, only 100-200 reported regression.
“Studies suggest that only one to ten percent of patients experience this issue,” she said when contacted recently.
She highlighted that performing Lasik surgery requires doctors to have at least 12 years of education and training.
"Ten to twenty years ago, the quality of lasers was lower and less advanced compared to now.
“Today, the chance of regression is very small, and complications are often due to factors such as inadequate follow-up," she said.
Dr Muhaya stressed the importance of regular follow-ups with assigned surgeons to address any post-surgery complications.
Consulting experienced professionals, she said, ensures appropriate care tailored to individual needs, offering better guidance than generic solutions.
She also clarified that regression did not mean the eyes would revert entirely to their original prescription but only by 200 to 300 degrees.
"Regular check-ups are important to track changes," she added.
Addressing viral stories about negative Lasik experiences, she advised those considering the surgery to avoid such news, which often exaggerates the risks.
"People tend to focus on negative news, while those with good experiences rarely share them," she said.
Dr Muhaya said other factors contributing to complications, such as eye strain from work, post-pregnancy symptoms and environmental influences.
She said that the optimal age for Lasik is 18 to 21, when the development of the eyeballs is stable.
For those over 48, multifocal intraocular lens surgery is often recommended instead.
Discussing the advancement of Lasik technology, she noted the high cost of modern machines, which can range from one to two million Ringgit per unit.
She also commented on the impact of misinformation spread on social media.
Dr Muhaya, who is one of the renowned ophthalmologists in the country, emphasised that the medical authority prioritises safety in surgery, highlighting that only human surgeons could perform the delicate procedure involving corneal flaps, despite advancements in Artificial Intelligence.
Meanwhile, EyeQ Chief Medical Director Dr Ajay Sharma also urged patients to prioritise personalised care and thorough assessment before undergoing Lasik surgery to avoid potential medical negligence.
“One should have a stable prescription for at least two years to ensure long-term success,” he said.
Dr Ajay said it was crucial to understand potential risks and maintain open communication with healthcare providers for optimal outcomes and preserving visual health.
