TORIC IOLs to correct Astigmatism during Cataract Surgery

Toric intraocular lenses

These are a 'premium intraocular lens' option, which in experienced hands can be offered to more than 50% of patients undergoing cataract surgery.

Because of Dr Rogers' considerable experience using 'Toric' intraocular lenses (IOLs) he can correct even relatively small amounts of a patient's “astigmatism” at the time of cataract surgery.

Toric intraocular lenses look very similar to ‘regular’ IOLs, however they are designed with a slight oval or ‘toric’ surface and must be precisely aligned inside the eye at a specific angle, depending on the shape and the 'total' power of the cornea's astigmatism in the eye.

Correction of astigmatism can allow much better vision and less dependence on spectacles.

Dr Rogers has had far more experience than most, having used toric intraocular lenses since 2009. He has inserted well over a thousand toric IOLs.

He is the only cataract surgeon in Southland/Otago (and one of few in New Zealand) using “Swept Source OCT” Biometry which measure both the  inside and the outside surfaces of the cornea to obtain the  ‘total power’ of the cornea for more precise IOL measurements and therefore better visual outcomes.

This is particularly important when deciding on the patient's suitability for a toric IOL, when calculating which Toric IOL power to use and for the best possible placement of this toric IOL.
