LASIK
LASIK - Laser-Assisted In Situ Keratomileusis - is today's most common refractive eye surgery with approximately 800,000 procedures per year in the United States. As of 2025, over 40 million LASIK surgeries have been performed worldwide.
LASIK is a type of refractive surgery that corrects myopia, hyperopia, and astigmatism. Performed by an ophthalmologist, LASIK uses a laser to reshape the cornea and improve visual acuity. For most patients, it offers a permanent alternative to glasses or contact lenses.
LASIK is similar to photorefractive keratectomy (PRK) but represents a more advanced surgical approach. For patients with thin corneas or high myopia, phakic intraocular lenses may be recommended instead.
Quick and minimally uncomfortable, LASIK provides rapid visual recovery, with many patients seeing 20/20 within 24 hours. Techniques such as mono-vision can also reduce the need for reading glasses for patients over 40, improving day-to-day life activities.
Who Are The Optimal LASIK Candidates?
Ideal candidates are at least 21 years old, have healthy eyes, and sufficient corneal thickness, since tissue is removed during surgery. Chronic dry eye, corneal disease, or other abnormalities may disqualify a patient. A comprehensive eye exam at Optometry At Redwood Shores in Redwood City ensures eligibility.
LASIK is elective and requires careful consideration of personal needs, potential benefits, and risks. While it often reduces dependence on corrective lenses, outcomes may vary, and perfect vision is not guaranteed. Discussing expectations with your eye care team is important for making an informed decision.
LASIK Procedure Overview
LASIK is an outpatient, two-step procedure, typically taking about 15 minutes for both eyes. First, a thin corneal flap is created and lifted, followed by laser reshaping of the cornea. The flap is then carefully repositioned.
Most patients report minimal discomfort during the procedure. The precision of the laser and the brief duration help make LASIK a highly predictable and safe procedure when performed by a qualified ophthalmologist.
Wavefront LASIK
Wavefront LASIK, or custom LASIK, uses computer-mapped laser treatment for precise correction, including subtle optical imperfections called higher-order aberrations. This method often provides sharper vision, improved night vision, and reduced risk of halos or glare compared to conventional LASIK. Wavefront-guided technology ensures the procedure is tailored to the unique shape of each patient’s eyes.
Post-Procedure Expectations
After surgery, patients use medicated eye drops and protective shields. Vision is often good enough to navigate safely, though driving is not advised immediately. Eye drops are continued for a week or more, and artificial tears may help with dryness.
Resting the eyes on the day of surgery is recommended, and dim lighting may help reduce discomfort. The day after surgery, most patients can resume normal activities, though rubbing the eyes should be avoided.
Follow-up visits may occur the day after surgery or as scheduled by your surgeon. Postoperative care can be provided at Optometry At Redwood Shores through a co-management agreement with your surgeon, helping patients in Redwood City feel confident about recovery.
Blurry Vision After LASIK
Vision typically stabilizes within days, though minor improvements may occur for months. If blurry vision persists, consult your LASIK surgeon. Enhancements may be considered if needed, or corrective lenses may be used temporarily. Our team is available to examine your eyes and discuss options if vision concerns remain.
Eyewear After LASIK
Even with good vision, protective eyewear is recommended outdoors. Sunglasses with 100% UV protection and polycarbonate lenses help prevent injury. Reading glasses may still be needed after age 40, and mild prescriptions can improve night driving comfort and safety.
Eye Care After LASIK
Routine eye exams remain important for ongoing eye health, including monitoring for glaucoma and other conditions. Regular exams help ensure vision remains stable and healthy following LASIK. Patients who continue with routine eye care enjoy the long-term benefits of clearer vision and healthier eyes.
