Research activities in the field of ophthalmology are becoming more and more important, since a number of issues related to the complex physical phenomena occurring inside the eye must be addressed. Different coupled physical mechanisms need to be studied, such as biological processes, heat and mass transfer, interaction with porous media, fluid structure interaction and others. Surgeries on human eyes can be optimized thanks to the improvement of knowledge, based on scientific research findings. The practical consequence is that post-operative complications can be reduced, with increase of life quality.
As concerns the posterior section of the eye, a relevant example of surgery is represented by vitrectomy, which is an intraocular surgical procedure involving removal of vitreous gel to release the vitreoretinal traction, in order to treat the retinal tear and epiretinal proliferation. The procedure requires the continuum infusion of fluids, such as balanced salt solution or air, with the primary aim to maintain a constant intraocular pressure during the removal of vitreous gel. In order to avoid hypothermal condition, with consequent influence on the biological changes in ocular tissues that affect the normal operating condition of human body, the temperature of the infusion fluids should be properly controlled by employing novel heating devices [1-2].
As concerns the anterior section of the eye, a relevant example of surgery is represented by the glaucoma curing techniques. Glaucoma is an eye illness that affects humans and other mammalians, leading to a stage of total blindness. It is a major concern for ophthalmologists, as it is the second cause of eye vision loss worldwide . Ageing and increased values of intraocular pressure (IOP) at the anterior chamber of the eye, generally above 21 mm Hg, are the main risk factors of glaucoma [4-6]. Therefore, curing treatments for glaucoma are targeted towards lowering IOP by means of various techniques. Among the available surgical procedures, the insertion of glaucoma drainage devices assumes a relevant role. These devices provide the increase of aqueous humour outflow, creating alternative outflow pathways, at the proximal region of conjunctiva and suprachoroidal space [4-8].
Patient-oriented based numerical models can be useful to further improve the present standards in the field of eye diseases. In fact, the use of a multidisciplinary technical-medical approach may provide a valuable engineering support to doctors, providing them with useful information based on specific patients’ needs, with consequent reduction of post?operative complications.
