Toric IOLs are now widely used to correct astigmatism for patients undergoing cataract surgery.
A cylinder component within the toric IOL corrects the astigmatism, so that light focuses properly on the retina. To do this, the cylinder component in the IOL must be aligned specifically to counteract the astigmatism coming from the cornea. The angle of the astigmatism is marked on the cornea to help you do this.
Several methods have been developed for astigmatism marking. This activity will discuss some of the corneal marking methods available and the challenges that arise with them.
Astigmatism marking for the cataract patient
Treating presbyopia is often considered the “holy grail” of anterior segment surgery.
While several approaches have been taken, there is no definitive treatment.
This activity will discuss the theory and development of multifocal lenses and the application of monovision for patients with presbyopia. Also, explored is some of the newer developments, and improvements in our knowledge, regarding multifocal IOL technology.
