An indentation intraocular pressure sensor (IIOPS) was designed and manufactured. It is based on piezoelectric polyvinylidene fluoride (PVDF) films. This sensor will help in the detection and diagnosis of intraocular pressure (IOP) in eye diseases like glaucoma. The pressure in the normal aqueous and vitreous phases is, on average, 15.5 mmHg and up of 21 mmHg when glaucoma exists. The proposed IIOPS offers a measurement range from 10–29 mmHg with a resolution of 1 mmHg and an accuracy of ±0.025.
