LASIK-based surgery is used to reduce myopic, hyperopic and astigmatic refractive error by changing the curvature of the corneal surface with excimer laser technology, allowing people to achieve good naked eye vision and life vision. The overall global patient satisfaction rate after LASIK averages 95.4% (87.2% to 100%). The gold standard for evaluating the quality of surgery is patient satisfaction and comfort, i.e., the ability to achieve the desired corrected visual acuity with good visual acuity for life through high quality surgery. High-quality refractive surgery includes three main components: excellent excimer laser surgical equipment; good surgical environment and excellent surgical technique; and personalized patient analysis and surgical design. All three are interrelated and one cannot be achieved without the other. The surgical technique has been developed and perfected, from the original pure superficial PRK, to LASIK, and gradually to the optimized superficial femtosecond laser flap, lamellar ultra-thin corneal flap, subbasal membrane cutting and superficial LASEK and EP-LASEK surgery. Patient Quality of Life and Satisfaction After Surgery In 2009, Dr. Kerry D. Solomon et al. reviewed the quality of life and satisfaction of patients after LASIK in the LASIK World Literature Review over a 20-year period from 1988 to 2008. Patients were 18 to 67 years old and had refractive error in the range of C22.75 to +7.00D. The overall global patient satisfaction rate after LASIK was noted to be an average of 95.4% (87.2% to 100%). The satisfaction rate is influenced by a number of factors: first, the influence of refractive status. It varies greatly across refractive status, with 95.3% satisfaction rate for myopic patients after LASIK and 96.3% for hyperopia. Second, satisfaction changed with chronological time. Patient satisfaction rates were found to range from 93.8% to 100% with a mean of 96.0% in articles from 1995 to 2000, increasing each year. The analysis of the study concluded that despite multiple clinical studies and technological innovations, LASIK surgery is still considered the most successful option and is currently the most mainstream refractive surgery, with 60% of adults in the United States affected by refractive error and the number of people undergoing this procedure increasing each year. Refractive surgery has also allowed people to enter professions that were previously closed to them because of their low vision. Excimer laser vision correction surgery is known to correct refractive errors and reduce dependence on glasses or contact lenses. The U.S. Food and Drug Administration (FDA) has conducted numerous clinical studies and rigorous reviews of LASIK surgical devices, which found that 97% of patients who underwent excimer laser keratomileusis achieved naked eye vision of 0.5 or better, and 62% achieved 1.0 or better, giving patients convenience, good and comfortable naked eye vision, and relatively low complications. Comparison of satisfaction with other cosmetic surgery procedures, such as botulinum toxin type A treatment (67% to 97%), breast augmentation (75% to 93.8%), rhinoplasty (51.5 to 94%), monopolar radiofrequency facial skin tightening (54.7% to 84%), and LASIK (87.2% to 100%), shows that they are procedures with higher satisfaction than other options, and are realistic procedures that can be performed It is a realistic procedure to perform. About 16.3 million patients worldwide have undergone the procedure to date. This type of surgery has been performed in China for almost 17 years (May 1993, Peking Union Medical College Hospital was the first to perform it in China), and there are now more than 1,000 hospitals or surgery centers nationwide, and the volume of surgery is increasing year by year, with about 1 million people receiving surgery this year. A retrospective study of 26743 patients ten years after refractive corneal surgery at Peking Union Medical College Hospital found 14,691 eyes in men and 29,889 eyes in women; ages 9-57 years (mean 27.2 years). Preoperative status: naked visual acuity 0.10±0.07, corrected visual acuity 0.98±0.37. 98.2% of ≥0.5, 92.1% of ≥1.0, 5.0% of ≥1.5; spherical lens -0.75~18.0D (C5.65± 3.24D); postoperative status: naked visual acuity 0.98±0.34; 100% of ≥0.5, ≥1.0 98.8%; 10.6% for ≥1.5. Spherical lens C0.001±0.058D. The actual correction was within the expected correction ±1.00, and the quality of life was satisfactory 98.7%. 2. Reasons for dissatisfaction and complications of patients after surgery Significant differences in quality of life were found in the study of 104 patients wearing frames, contact lenses, and each undergoing refractive surgery, respectively. Specifically, patients who underwent refractive surgery had a higher quality of life satisfaction rate than those who wore contact lenses or glasses, which greatly improved the quality of vision. The most common complaints of dissatisfaction and poor visual quality after surgery were residual refractive error, poor near vision, dry eyes, low vision in dim light, and nighttime halos. In the United States, 95.2% (91.4% to 100%) of the operated patients were satisfied and 4.8% (0% to 6.2%) were dissatisfied. In countries other than the United States, 95.6% (87.2% to 100%) of postoperative patients were satisfied and 4.4% (0% to 7.8%) were dissatisfied. The gradual increase in patient satisfaction with the age of the procedure and the gradual decrease in dissatisfaction over time are very directly related to the gradual improvement in surgical equipment, the gradual improvement in the surgeon’s skill and ability to deal with problems, and the gradual understanding of this technology by patients. Dry eye is a major cause of patient dissatisfaction, although successful vision correction and dry eye is reversible with effective medication for dry eye. Careful questioning of the details of the preoperative history, thorough preoperative examination, and effective treatment in advance can prevent exacerbation of the dry eye condition after surgery. Although laser vision correction can cause temporary dry eye, modern superficial and thin flap surgery has resulted in a lower incidence and significantly shorter duration of dry eye associated with LASIK surgery. Treatment of dry eye patients is available with new artificial tear preparations most patients have reduced or disappeared symptoms. In conclusion, patient satisfaction can be seen as a multifaceted reflection on whether the surgery met the patient’s physical, emotional and monetary expectations and whether the patient was also physically and/or psychosocially affected. Ophthalmologists have traditionally focused on postoperative visual acuity and the presence or absence of complications with keratomileusis. However, measurement of visual acuity alone does not adequately reflect the outcome of the procedure. It also includes some impact on the patient from post-operative life visual changes, such as changes in appearance, lifestyle, environment, confidence, interests, and overall quality of life. This is the reason why people also expect a variety of new corneal surgeries with higher satisfaction rates.
