People who are looking for flawless vision often have to choose which type of refractive surgery to have. In this arena, Photorefractive Keratectomy (PRK) and Laser-Assisted In Situ Keratomileusis (LASIK) are popular rivals. It becomes essential to comprehend the distinctions between these operations at Smart Vision Eye Hospital, which is renowned for its cutting-edge technology and personalized attention.
Photorefractive Keratectomy involves using an excimer laser to reshape the cornea after removing the corneal epithelium, the outermost layer of the eye. Throughout the healing period, the epithelium regrows.
On the other hand, LASIK surgery involves creating a corneal flap, raising it, and using a laser to reshape the cornea. Subsequently, the flap is relocated, leading to a faster recovery than with PRK.
Although PRK surgery has excellent long-term results, the healing period is slightly longer since the corneal epithelium takes time to repair. During the first healing phase, patients could have pain and blurred vision.
LASIK has a shorter recovery time, with patients often detecting improved vision within a day or two following the treatment. LASIK treatment is a superior alternative for people who want rapid visual rehabilitation because the corneal flap is generated sooner, which accelerates the healing process.
PRK is a suitable option for people whose corneas are thinner or who are not qualified for LASIK because of specific corneal conditions. It is also preferred by people who lead an active lifestyle because there is no chance of flap-related issues.
LASIK is often advised for people with thicker corneas and those who want a quick recovery. On the other hand, people who play contact sports or engage in other activities, where there are chances of eye injuries may find the formation of a corneal flap concerning.
Since the corneal epithelium is removed, inflammation and discomfort are generally greater in the first few days following PRK. However, as the epithelium regenerates, this discomfort lessens.
It is well known that there is little discomfort experienced both during and after the treatment. As a natural bandage, the corneal flap lessens the possibility of chronic discomfort.
PRK is the best option for anyone looking for long-lasting visual results because it has exceptional long-term stability. The surgery is more resilient because there is no need for a corneal flap.
The majority of individuals who get LASIK report long-term improvements in their vision, often lasting years. Over the period, there might be an unlikely chance of encountering issues with the corneal flap.
After LASIK, it will take a few days or less to see clearly. PRK takes around one month, in contrast. The outcome will be the same if the surgery is done correctly by a qualified, skilled surgeon.
Outcomes from PRK surgery are similar to those from LASIK; however, because new epithelial cells grow and cover the surface of the eye over a few days, early recovery from PRK surgery is typically delayed. Additionally, in the initial days following surgery, there is a modest increase in the risk of impaired vision and eye infections.
Even though LASIK surgery results in permanently better vision for the great majority of patients, some patients could require additional treatments to achieve the desired result. It is conceivable, and in fact, might be the safest option, to undergo PRK following LASIK. It is not always a good idea to have another LASIK procedure done a few years after the first one because there is a considerably larger chance of epithelial ingrowth. In that instance, PRK would be suggested as a follow-up eye treatment.
With the latest technology, PRK and LASIK procedures are carried out precisely and safely at Smart Vision Eye Hospital. Patients receive individualized consultations to select the best technique based on their specific eye characteristics and lifestyle, as part of the hospital's dedication to patient-centric care.
Deciding between PRK and LASIK is crucial in the field of vision correction. Individuals can embark on their journey to visual clarity with confidence at Smart Vision Eye Hospital, where innovation meets competence.A CLEAR OVERVIEW VIDEO ON PRK AND LASIK EYE SURGERY
