Corneal structural and morphologic distortion of any degree usually has a negative impact on quality of vision, and patients can often become symptomatic even at an early stage.

Anterior lamellar keratoplasty continues to evolve, with newer surgical techniques and improved surgical instruments, and this progressive, forward movement is transforming the landscape of corneal surgery.
