简要总结
Phakic intraocular lenses (pIOL) have proven to be a great alternative to corneal refractive surgery in certain situations. They offer several advantages over corneal techniques, such as being suitable for high myopes and causing relatively fewer higher-order aberrations. In addition, pIOLs have been shown to provide better retinal image magnification and higher contrast sensitivity compared to laser in situ keratomileusis, regardless of whether the myopia is low or high.
