Final answer:
Strabismus and corneal scissors are involved in ophthalmic surgeries, with strabismus surgery addressing eye misalignment and corneal scissors being used in LASIK procedures to reshape the cornea and correct vision.
Step-by-step explanation:
Strabismus and corneal scissors are most often used in ophthalmic procedures. Strabismus surgery corrects the misalignment of the eyes, whereas corneal scissors are utilized in surgeries involving the cornea, such as in LASIK (Laser-Assisted in situ Keratomileusis). LASIK is a procedure where the top layer of the cornea is surgically peeled back and underlying tissue is ablated with an excimer laser to correct vision issues such as nearsightedness, farsightedness, and astigmatism. The precision of the LASIK procedure with the use of a computer-controlled laser allows for the accurate reshaping of the cornea, as the cornea accounts for about two-thirds of the eye's power. The high-intensity laser ablates the corneal surfaces with controlled bursts, resulting in the desired changes to the eye's focusing ability. This method has proven to be the most successful and widely used method of laser vision correction.
