Intraocular lens power calculation in short eyes [PDF]
Eye, 2007 To compare the accuracy of the Hoffer Q and SRK-T formulae in eyes below 22 mm in axial length, using biometry measured with partial coherence inferometry (PCI), without a customised ACD constant.Data were retrospectively and prospectively collected by identifying eyes of axial length below 22 mm in the records of the intraocular lens (IOL) master and ...

Cataract Surgery following Sequential Myopic and Hyperopic LASIK
Case Reports in Ophthalmology, 2018 We report a case of patient dissatisfaction after sequential myopic and hyperopic LASIK in the same eye. We discuss the course of management for this patient involving eventual cataract extraction and intraocular lens (IOL) implantation with attention to

Astigmatism correction with toric intraocular lens during cataract surgery
Kerala Journal of Ophthalmology, 2020 Currently toric intraocular lens (TIOL) implantation is the most reliable method to correct pre-existing corneal astigmatism of 1D or more at the time of cataract surgery. A good surgical outcome depends on proper patient selection, accurate preoperative
