What is a common application of lasers in ophthalmology?

A common application of lasers in ophthalmology involves treating cataracts and correcting refractive errors. In cataract surgery, lasers are often used for procedures such as capsulotomy, where the clouded lens capsule is opened, allowing for better vision restoration after the cloudy lens is removed. Additionally, laser technology plays a significant role in refractive surgeries, such as LASIK or PRK. These procedures utilize lasers to reshape the cornea, allowing individuals with vision impairments like nearsightedness, farsightedness, and astigmatism to achieve clearer vision without the need for glasses or contact lenses.

While other options involve laser applications in different fields, they do not specifically pertain to the outcomes directly related to ophthalmology. For instance, tattoo removal is primarily done in dermatology, and enhancements for night driving or cosmetic features pertain more to general cosmetic procedures rather than directly to the core applications of lasers in eye care. Thus, the use of lasers in treating cataracts and correcting refractive errors is a well-established and crucial practice in the field of ophthalmology.
