Laser Safety Glasses is a nonsurgical procedure that uses laser technology to correct vision problems such as nearsightedness, farsightedness and astigmatism. The two most common types of vision correction are LASIK and PRK.
LASIK (Laser-Assisted In-Situ Keratomileusis)
LASIK is the most common and popular type of vision correction procedure. It involves using a laser to reshape the cornea, the clear front covering of the eye. Here is a brief overview of the LASIK procedure:
- An eyecare professional numbs the eye with anesthetic drops and uses a laser to create a thin flap in the cornea. This flap is gently folded back to expose the underlying corneal tissue.
- A excimer laser then reshapes the exposed corneal surface by removing microscopic layers of tissue. This changes the shape of the cornea and corrects refractive errors like nearsightedness and farsightedness.
- Once laser reshaping is complete, the corneal flap is put back into position. Laser Safety Glasses heals quickly and helps stabilize the eye during healing. The entire procedure takes around 15-20 minutes for both eyes.
LASIK provides quick visual recovery allowing most people to resume their normal daily activities within a day. It delivers lasting vision correction results for many patients. However, success and final vision outcomes can depend on factors like pre-operative exams, patient cooperation and post-op care instructions.
PRK (Photorefractive Keratectomy)
In PRK, the protective outer layer of the cornea called the epithelium is surgically removed before laser reshaping. This exposes the underlying corneal tissue which is then sculpted by the excimer laser to correct vision. Here are some key points about PRK:
- It doesn't require creating a corneal flap like in LASIK which some may see as an advantage over LASIK. However, this means deeper tissue ablation and a longer recovery time.
- Visual recovery after PRK can take around 5-7 days as the eye must heal and grow new epithelial cells. Pain and discomfort during healing is typically more with PRK compared to LASIK.
- Due to its gentler tissue removal method compared to LASIK, PRK may be better suited for patients with thin or uneven corneas where creating a flap could be risky.
- Long term vision outcomes are generally similar between LASIK and PRK when performed by experienced surgeons. Success rates are high but vary based on pre-op exams and post-op care adherence.
Laser Safety Glasses Candidates and Consultation
Not everyone is a suitable candidate for laser eye surgery. Some factors eyecare professionals consider include:
- Refractive error - Candidates usually have nearsightedness (-3.00 diopters or less), farsightedness (+2.00 diopters or less) or astigmatism. Higher prescriptions may still be treated.
- General eye health - Patients must not have any active ocular conditions like cataracts, glaucoma, dry eyes or keratoconus that could impact healing or success.
- Corneal thickness - Corneas must be of sufficient thickness/strength to withstand laser treatment and healing. Thin corneas may preclude LASIK.
- Expectations - Laser vision changes are intended for distance vision. Reading glasses may still be needed. Candidates must understand limitations and commit to follow ups.
Before undergoing vision correction, it's important to have a thorough consultation with an experienced ophthalmologist or optometrist. Screening tests like eye exams, corneal topography and wavefront analysis help determine eligibility and develop a personalized treatment plan. Addressing all pre-op concerns leads to well-informed consent and optimal results.
