Meanings of corneal astigmatism in English

A new quantitative keratoscope used specially for ocular microsurgery to measure corneal astigmatism is reported.

The keratoscope could be used to measure the corneal astigmatism quantitatively specially for ocular microsurgery.

Postoperative refractive astigmatism with the toric IOL was independent of preoperative corneal astigmatism axis orientation.

The axis of preoperative corneal astigmatism was not a significant factor in the toric IOL group.

Postoperative refractive astigmatism between groups and subgroups was compared based on the orientation of preoperative corneal astigmatism.

The corneal astigmatism can be measured by changing the power of the combined lens to adjust the corneal ring images.

The mean preoperative corneal astigmatism was 1.06 D, with no significant difference between IOL groups or by axis of astigmatism.

Objective: To investigate the ocular optical imaging quality among corneal astigmatism subjects under different corrections by using the Point Spread Function analysis system (PSF).

The axis of corneal astigmatism was also found to be significantly correlated with the angle of the palpebral fissure (r = 0.317; P = 0.005).
