[Several controversial issues in astigmatism correction in cataract surgery]

Area of Science:

• Ophthalmology
• Refractive Surgery
• Corneal Astigmatism Management

Background:

• Cataract surgery now aims for refractive correction, increasing patient demand for high visual quality.
• Current astigmatism correction in cataract surgery often yields suboptimal results due to unestablished principles.

Purpose of the Study:

• To provide guidance on managing corneal astigmatism during cataract surgery.
• To address key issues in astigmatism correction for improved surgical outcomes.

Main Methods:

• Review of authoritative guidelines, expert consensus, and relevant literature.
• Discussion of decision-making, estimation methods, calculation formulas, and surgical techniques.

Main Results:

• Identified critical factors for successful corneal astigmatism correction.
• Provided evidence-based suggestions for optimizing surgical planning and execution.

Conclusions:

• Effective management of corneal astigmatism is crucial for achieving refractive goals in cataract surgery.
• Standardized approaches to astigmatism assessment and correction are needed for predictable visual outcomes.
