The document discusses the selection criteria and management strategies for toric intraocular lenses (IOLs) in patients with astigmatism. Key considerations include the need for astigmatism correction, pre-operative assessments of magnitude and axis, and factors for successful outcomes. The author, Dr. Ismail Hamza, provides five pearls for preoperative preparation and assessment to optimize patient results.

2. 1. Do we need to correct astigmatism?
2. For whom?
3. What to target in “astigmatism management”?
4. How to correct it?
5. What about the other eye if already aphakic and
astigmatic?

3. Year 2013, Toric cases
