In the quest for perfect vision without glasses or contact lenses, LASIK has emerged as a popular solution for millions worldwide.
Many patients who are excited about the possibility of clear vision but hesitant due to safety concerns.
LASIK has a good, constant track record. Complications are rare, and most people are satisfied with the results. Certain side effects, particularly dry eyes and temporary visual issues (such as glare), are fairly common.
Understanding LASIK
LASIK (Laser-Assisted In Situ Keratomileusis) is a surgical procedure that uses laser technology to reshape the cornea, correcting vision problems including nearsightedness, farsightedness, and astigmatism. The procedure typically takes less than 30 minutes for both eyes and has transformed vision correction since its FDA approval in the late 1990s.
Modern LASIK has evolved significantly with technological advances like wavefront-guided systems and femtosecond lasers replacing traditional microkeratomes. These improvements have enhanced precision and safety, leading to the best outcomes for patients.
LASIK Safety: What the Data Shows
When evaluating any medical procedure, we turn to evidence and statistics. The data on LASIK safety is reassuring:
- Patient satisfaction rates consistently hover around 96%, according to the latest consensus studies
- Over 90% of patients achieve 20/20 vision or even better after LASIK
- Serious complication rates are extremely low, estimated at less than 1%
- The FDA’s PROWL (Patient-Reported Outcomes with LASIK) studies found that the majority of patients reported no visual symptoms after surgery
A landmark 2023 study published in the Journal of Cataract & Refractive Surgery followed 13,000 LASIK patients over five years and found that 98.6% would recommend the procedure to friends and family. This high satisfaction rate speaks volumes about both safety and effectiveness.
Modern, comprehensive screening techniques have dramatically reduced risks by properly identifying unsuitable candidates before surgery. This proactive approach to patient selection has been a game-changer for LASIK safety.

Are You a Good Candidate?
The most important factor in LASIK safety is proper candidate selection. Not everyone is suitable for LASIK, which is why Comprehensive Eye Screening is essential.
A thorough consultation with a qualified, experienced ophthalmologist is the only way to determine if you’re a suitable candidate. This screening process is your first safeguard against potential complications.
At Shinagawa Lasik & Aesthetics, we conduct comprehensive evaluations using advanced diagnostic equipment to ensure we recommend LASIK only for those who will benefit safely from this life-changing procedure.
High Success Rates and Patient Satisfaction
One of the most compelling indicators of LASIK’s safety is its success rate. According to a study published by the Journal of Cataract and Refractive Surgery, over 95% of LASIK patients achieve 20/20 vision or better.
Patient satisfaction is equally impressive. LASIK, according to the most recent unified studies, holds a 96% satisfaction rate among recipients, making it one of the highest-rated elective procedures.
These high success and satisfaction rates are not coincidental. They are the result of meticulous preoperative screenings, individualized treatment plans, and advanced surgical techniques.

FAQ’s : Addressing Common Concerns
“Can LASIK cause blindness?”
Total blindness from LASIK is extraordinarily rare. In the millions of procedures performed worldwide, there are virtually no documented cases of complete blindness resulting directly from LASIK when performed by qualified surgeons.
“Will I need glasses again after LASIK?”
LASIK corrects your vision at the time of surgery. It doesn’t prevent age-related vision changes. Some patients may eventually need reading glasses due to presbyopia, but this would happen regardless of having LASIK.
“Is the procedure painful?”
Most patients report minimal discomfort during and after LASIK. Numbing drops make the procedure virtually painless, and any post-operative discomfort typically resolves within hours.
Choosing Safety with Confidence
When performed on qualified candidates by experienced surgeons using modern technology, LASIK has proven to be remarkably safe and effective. The key factors influencing safety are thorough pre-operative screening, surgeon experience, and appropriate patient expectations.
