Transcript of Laser Eye Surgery Assignment - Science

Laser Eye Surgery By Matthew and Cameron Photo Refraction Keratectomy (PRK) Length of Procedure for Laser Eye Surgery Costs of Laser Eye Surgery LASIK (Laser-Assisted in Situ Keratomileusis) PRK (Photo-Refraction Keractectomy) Length of Recovery: Laser Epithelial Keratomileusis (LASEK) The Length of a PRK Procedure is a total
of 15 minutes per eye. The cost of the PRK Procedure is $1695 per eye.
The cost of the LASIK Procedure is $490 per eye.
The cost of the LASEK Procedure is also $490 per eye PRK - Can take two days to one week.
LASIK - Can take two days to one week.
LASEK - Can take two days to one week With LASIK, a thin flap is cut into the eye's surface and then lifted. Laser energy is applied to the eye for reshaping, and the flap is replaced to serve as a type of natural bandage for quicker healing. Photo -refractive keratectomy, or PRK, is a type of laser eye surgery used to correct mild to moderate nearsightedness, farsightedness, and/or astigmatism. A LASEK procedure involves preserving the extremely thin epithelial layer by lifting it from the eye's surface before laser energy is applied for reshaping. After the LASEK procedure, the epithelium is replaced on the eye's surface. Laser Assisted in Situ Keratomileusis (LASIK) AND Types of Procedures For Laser Eye Surgery PRK - Allowed to drive in 6-8 weeks
LASIK - Allowed to drive in 6-8 weeks
LASEK - Allowed to drive in 6-8 weeks The Length of a LASIK Procedure is a total of 15 minutes per eye. Laser-Assisted Sub-Epithelial Keratectomy (LASEK) AND The Length of a LASEK Procedure is a total of about 15 minutes per eye. All laser vision correction surgeries work by reshaping the cornea, or clear front part of the eye, so that light traveling through it is properly focused onto the retina located in the back of the eye. There are a number of different surgical techniques used to reshape the cornea. During PRK, an eye surgeon uses a laser to reshape the cornea. This laser, which delivers a cool pulsing beam of ultraviolet light, is used on the surface of the cornea, not underneath the cornea. Positive Benefits and Drawbacks to Laser Eye Surgery CONS
-After the surgery, you may not be able to produce enough tears which can lead to your eyes becoming dry
-You can have hazy vision for a few days after the surgery
-Halo Effect: During low light levels, you can see fazed images
-Being able to see well without glasses or contacts
-Greater choices for sunglasses
-Fast and easy process with not too much pain
-After the changes to your eyes, you cannot worry about your glasses or contacts Success Rate for Laser Eye Surgery PRK: About an 80% success rate

LASIK: About a 40% success rate

LASEK: Very similar to LASIK but the healing process can take longer and more patients experience post-surgical pain Alternatives to Laser Eye Surgery -Lensectomy and IOL
-ICL (Intraocular contact lens)
-Intacs (intracorneal rings)
-Laser Thermal Keratoplasty
-Radial Keratotomy
-Automated Lamellar Keratectomy
-Astigmatic (Arcuate) Keratotomy
-Epikeratophakia Thank you for checking out our prsentation
