Vienna: Refractive Surgery Didactic Course (Part 2) - Multiple Choice Questions

Question Title

* 1. Name and/or Badge ID Number:

N. Hirnschall
Discussion of case reports

Question Title

* 2. After IOL implantation in eyes with previous refractive surgery a refractive surprise can occur, because

the altered ratio between the anterior and posterior corneal surface makes the keratometric index invalid

the corneal curvature radius is measured out of the optical zone

the effective lens position is erroneously predicted if such a prediction is based on the post-refractive surgery corneal curvature

the refractive index of the cornea is changed leading to a relevant measurement error of the axial eye length

the shape of the posterior cornea changes after refractive surgery resulting in an overestimation of the total

J. Guell
Refractive reoperations and enhancements

Question Title

* 9. Which statement is false about bioptics:

It was originally described because of a technical limitation in phakic IOL power

It is used to improve final quality of vision

It is considered any combination of corneal and intraocular refractive surgery

It is considered only the combination of a PC phakic IOL and LASIK

Lift the flap clean with absolute alcohol

PTK on the stromal bed

Lift the flap, clean both stromal sides of the cyst and suture the lenticule
