Bioptics
For extreme nearsightedness, a combination of a lens implant (to correct up to - 20 dpt) and laser eye surgery (to correct another -3 to -5 dpt with or without astigmatism) can be used. The procedure, called Bioptics, requires two different operations.
Indication
— Extreme nearsightedness upt to -25 dpt.
— over- or undercorrection or astigmatism after lens implantation
Properties
— see LASIK and lens implant
| First procedure | |
 |
Preparation of the flap On the day of the lens implant, the LASIK flap will be cut first. |
 |
The lens implantation follows. |
| Second procedure (ca. 3 month later) | |
 |
The flap, prepared during the first procedure, is lifted. |
 |
The cold excimer-laser ablates the cornea by burning off small amounts of tissue. |
 |
The flap is placed back and covers the ablation area. There is no need to apply stitches. |
