This layer allows the even distribution of the tears on the cornea and the protection of all the corneal surface by the tear film.
Then, when the toric IOL is implanted during the cataract procedure, the surgeon rotates the IOL so the markings on the IOL are aligned with the markings on the cornea to insure proper astigmatism correction.
However, one of the mostcommon problems is the appearance of scars on the cornea, which worsens vision and creates a very blurred image.
When toric IOLs are implanted in the cataract procedure,they are rotated so the markings on the IOL are aligned with the ones on the cornea to assure proper astigmatism correction.
Next the LASIK surgeon will use either a laser or an instrument called a microkeratome to create a very thin,circular flap on the front of the cornea.
