Based on the provided reference, while myopia can exist with varying degrees of severity, -10.0 D is mentioned as the maximum power considered for LASIK surgery.
Understanding myopia power limits is particularly relevant when considering vision correction procedures like LASIK. According to the reference from Visual Aids Centre, specific power ranges are considered suitable for different surgical options.
Myopia Power Limits for Surgery
The reference outlines the following power limits in the context of LASIK surgery:
- Required Power Limit for Surgery: -0.5 D to -8.0 D
- Considered Ideal for Surgery: -8.0 D
- Maximum Number Required for the Surgery (LASIK): -10.0 D
Powers beyond -10.0 D are also associated with myopia, but the reference indicates that LASIK must be avoided in such cases. For these higher powers, alternative techniques like ICL (Implantable Collamer Lens) are suggested.
Here is a summary based on the source:
| Category | Myopia Power (Diopters, D) | Notes |
|---|---|---|
| Required Limit for Surgery | -0.5 to -8.0 | Range considered suitable for surgery |
| Ideal Power for Surgery | -8.0 | Considered the ideal value for surgery |
| Maximum for LASIK Surgery | -10.0 | Highest power typically considered for LASIK |
| Beyond LASIK Limit | > -10.0 | LASIK avoided; ICL or other options viable |
This information highlights that while -10.0 D represents a practical maximum for the LASIK procedure according to this source, myopia itself can have powers exceeding this value, requiring different treatment approaches.
