The person has a good visual acuity close by, but blurred sight in distance.
This is the newest technique with which almost all refractive errors are corrected. Lasik is a combination of microsurgery and laser technology.
The excimer laser is directly applicated on the corneal surface. These causes a superficial lesion which is painful during 48 to
72 hours postoperatively. Hence, in most cases a protective contact lens is temporally applied. The eye sight stabilises during the following weeks or months.
This technique (TransPRK) is meant for people with a thin cornea or other kind of corneal defect, which cannot be treated with lasik technique.
In the case of very large refractive errors, or if lens blurring is present, it is better to place an artificial lens in the eye.
Small Incision Lenticule Extraction with SMILE is the most recently developed type of laser eye surgery. It’s a minimally invasive procedure that can correct various vision impairments such as nearsightedness and astigmatism.
