Radial lenticule extraction (RLE) is a refractive surgery procedure used to correct myopia (nearsightedness) and astigmatism. It utilizes a femtosecond laser to create a precise, disc-shaped piece of corneal tissue (lenticule) within the cornea, which is then removed through a small incision, reshaping the cornea and improving vision. This differs from LASIK, where a flap is created, and from SMILE, where the lenticule is removed through a smaller keyhole incision.
Precise vision correction procedures offer significant advantages for individuals seeking freedom from glasses or contact lenses. These techniques can enhance quality of life by improving visual acuity for various activities, including driving, sports, and professional tasks. The development of sophisticated laser technology has allowed for greater precision and predictability in refractive surgery, leading to improved outcomes and faster recovery times. Factors influencing procedure selection often include the degree of vision correction required, individual corneal characteristics, and lifestyle considerations.
