Do contact lenses only come in one size?

NO, contact lenses can come in different size. Usually contacts for astigmatism are larger than normal contacts. Also the thickness can be different to fit your eyes because people have different base curves.

What are the risks of wearing Extended Contacts?

Although extended contacts are designed for long time wearing, it is still not always safe to wear them. Extended contacts still need to be cleaned regularly and if not, the opportunity for growth of bacteria would increase, which can endanger the health of the eye.

Is it normal for astigmatism contact lenses harder in the middle than the outsides?

YES, it is just that type. Lenses for astigmatism ( toric lenses) are all like that. I think they are more easy to wear than regular soft contacts as they are harder in the middle part.

What is the ophthalmoscope used for in an eye exam?

Ophthalmoscopy is done as part of a routine physical or complete eye examination. It is used to detect and evaluate symptoms of retinal detachment or eye diseases such as glaucoma. In patients with headaches, the finding of swollen optic discs, or papilledema, on ophthalmoscopy is a key sign, as this indicates raised intracranial pressure (ICP) which could be due to hydrocephalus, benign intracranial hypertension (aka pseudotumor cerebri) or brain tumor, amongst other conditions. Cupped optic discs are seen in glaucoma. In patients with diabetes mellitus, regular ophthalmoscopic eye examinations (once every 6 months to 1 year) are important to screen for diabetic retinopathy as visual loss due to diabetes can be prevented by retinal laser treatment if retinopathy is spotted early.
