Patients' Satisfaction After LASIK

The aim of this study is to evaluate the level of satisfaction, functional vision and quality of life outcome of patients after LASIK surgery.

Study Overview

• Status: Unknown
• Conditions: Refractive Errors
• Intervention / Treatment: Device: slit lamp

Detailed Description

The feeling of sight in human is usually taken as the most significant factor for fathoming and receiving data from environment and, thus, assumes a significant role in regulating most human exercises and practices. Accordingly, any harm to this sense may significantly influence an individual's adjustment with environment.1

Refractive error can be explained as an eye condition in which incoming light rays are not focused on the photoreceptor layer of the fovea, resulting in blurred vision. Of the refractive errors, myopia, hyperopia, and astigmatism are the 3 most common types. In myopia, the incoming light rays are focused in front of the fovea, whereas in hyperopia, they are focused beyond the fovea. Astigmatism is typically explained by irregularities in the cornea (corneal astigmatism) and crystalline lens (lenticular astigmatism), which results in differential focusing of parallel rays through different corneal and lenticular meridians.The refractive surgery has a very important role helping subjects to get rid of contact lenses and spectacules.2-3

Laser-assisted in situ keratomileusis (LASIK) is the most popular refractive surgery performed to correct refractive errors of the eye, including myopia, hyperopia, and astigmatism. LASIK surgery has been reported to yield significantly improved patient reported visual outcomes.1 The result is the patient's independence from glasses and contact lenses. Many studies have reported that LASIK surgery can improve not only visual function,1 but also patients' quality of life (QOL).2,4-10

Patient-reported outcomes also revealed that LASIK can maximize patient satisfaction and quality of life by minimizing the onset of visual and dry eye symptoms.11 Happiness or positive emotions are now regarded as a critical component of health.12 With the introduction of the discipline of positive psychology in the late 1990s, many scientific investigations of happiness have resulted in the development of the proposal that happiness or positive emotions are highly beneficial for physical and mental health.12-19
