Laser in situ keratomileusis (LASIK) is a common surgery for vision correction. This review examines why some patients experience regression of their corrected vision after LASIK and discusses prevention and treatment options.
Area of Science:
- Ophthalmology
- Refractive Surgery
- Corneal Science
Background:
- Uncorrected refractive errors are a primary cause of global visual impairment.
- Laser in situ keratomileusis (LASIK) is the predominant surgical method for correcting refractive errors.
- Post-LASIK regression, a return of refractive error after surgery, is a persistent challenge despite advancements.
Purpose of the Study:
- To explore the mechanisms behind refractive regression following both myopic and hyperopic LASIK.
- To identify predisposing risk factors associated with post-LASIK regression.
- To review the clinical course, preventative strategies, and current therapies for post-LASIK regression.
Main Methods:
- Literature review of studies on LASIK outcomes and regression.
- Analysis of mechanisms contributing to refractive changes post-LASIK.
- Synthesis of data on risk factors, clinical presentation, and management options.
Main Results:
- Refractive regression after LASIK is a common phenomenon with significant long-term implications.
- Various factors contribute to regression, necessitating a comprehensive understanding.
- Current strategies exist for prevention and management, though challenges remain.
Conclusions:
- Understanding the mechanisms and risk factors of post-LASIK regression is crucial for improving patient outcomes.
- Further research into advanced preventative and therapeutic strategies is warranted.
- Addressing post-LASIK regression can enhance long-term visual performance and patient quality of life.

Multiple Regression
Farmers can use multiple regression to determine the crop yield based on more than one factor, such as water availability, fertilizer, soil properties, etc. Here, the crop yield is the response or dependent variable as it depends on the other independent variables. The analysis requires the construction of a scatter plot...

Regression Analysis
In regression analysis, a regression equation is determined based on the line of best fit– a line that best fits the data points plotted in a graph. This line is also called the regression line. The algebraic equation for the regression line is called the regression equation. It is represented as:
