Why the eyes can still form an image after the lens has been removed by a surgery?

After lens removal surgery, such as cataract surgery, the eye can still form an image because the cornea and the retina are intact and functional. The cornea helps to refract light, focusing it onto the retina, which processes visual information. While the absence of the lens affects the eye's ability to focus light sharply, many patients can still perceive images, often with the aid of corrective lenses or intraocular implants. Thus, the basic mechanisms of vision remain operational even without the natural lens.
