TORIC IOLs (to correct Astigmatism) during Cataract Surgery
Toric intraocular lenses
These are a 'premium intraocular lens' option, which in experienced hands can be used in more than 50% of eyes undergoing cataract surgery.
Toric intraocular lenses look similar to ‘regular’ IOLs, however are designed with a curved (‘toric’) surface. They must be precisely aligned inside the eye at a specific angle, depending on the shape and the 'total' power of the eye's astigmatism.
Correction of astigmatism can allow much better quality vision and less dependence on glasses.
Dr Rogers has had more experience than most, having used toric intraocular lenses for 15 years.
He is the only cataract surgeon in Southland/Otago using “Swept Source OCT” Laser Biometry which measures both the inside and the outside surfaces of the cornea to obtain the ‘total power’ of the cornea for more precise IOL measurements and 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 the precise alignment of this toric IOL.
