Why do patients with high myopia choose PIOL? Uncover the mystery!
In the field of eye surgery, myopia correction technology is changing rapidly, and patients with high myopia often face a dilemma of choice. As technology advances, many patients choose implantable intraocular lenses (PIOLs) as a vision correction solution. This article will discuss the advantages, use and reasons for patient selection of PIOL.
What is PIOL?
An implantable intraocular lens (PIOL) is a lens that is surgically implanted into the eye to correct refractive errors. Unlike the traditional lens implanted after cataract surgery (ie, a pseudophakic lens), a PIOL does not move. Except for the natural lens of the eye.
Challenges of high myopia
For patients with high myopia, laser corrective surgeries such as LASIK and PRK are often limited because these procedures carry greater risks with high myopia. PIOL provides a safe and effective alternative that allows patients to correct their vision without removing the natural lens.
Advantages of PIOL
PIOL can correct a wider range of refractive errors, including high myopia from -5 to -20 degrees.
PIOL can not only safely treat high myopia, but also preserve the adjustment function of the natural lens after surgery, which is a major advantage over other surgeries. Additionally, PIOL is removable, meaning it can potentially be adjusted or replaced if the patient is not satisfied with the visual results.
Possible risks and limitations
Although the risks of PIOL are relatively small, there are still some complications, such as glare, halos and cataracts, especially if long-term wear is required. Before patients undergo surgery, a comprehensive preoperative evaluation is required, including measurement of anterior chamber depth.
Suitable patient groups
PIOL is particularly suitable for patients over the age of 21 who have had stable refraction for at least six months. PIOL is not recommended for younger patients and those with existing eye disease, such as uveitis.
Summary and Outlook
With the assistance of today's technology, PIOL has become an ideal choice for patients with high myopia, not only providing excellent vision correction options, but also reducing recovery time after surgery. As the technology develops further, future PIOL technology will look forward to more improvements and optimizations. However, should patients with high myopia carefully consider the potential risks and make a comprehensive assessment before choosing surgery?
