The aim of the study was to identify whether preoperative corneal astigmatism can influence corneal biomechanics and the assessment of intraocular pressure (IOP) following micro-incision phacoemulsification.

Inclusion Criteria:

• diagnosis and qualification for cataract surgery, corneal astigmatism of equal to or less than 2.25 Dcyl

Exclusion Criteria:

• corneal astigmatism higher than 2.25 Dcyl, history of any other corneal disease (infection, trauma, ulceration, autoimmune inflammation, Fuchs Dystrophy, keratoconus, corneal scars, preoperative insufficiency of corneal endothelium), glaucoma and chronic use of non-glaucoma eye drops, blepharitis, dry eye, use of contact lenses diabetes or a history of corneal refractive surgery

39 patients diagnosed with cataracts were enrolled in the study
