Brief Summary
Serum eye drops (SEDs) are used to treat patients with extreme dry eyes and other corneal defects. Serum is used in severe ophthalmic cases where conventional eye drops (artificial tears) have insufficient effect. The use of SEDs in dry eye patients usually has a rapid effect. Most patients claim the effect to be instantaneous, and all symptoms improve within 48 hours. There is evidence suggesting that substances in serum may help in the healing of epithelial defects, such as epidermal growth factor, fibroblast growth factor, fibronectin, and/or vitamin A. However, the precise serum factor responsible for alleviating the patient's complaints is currently not known. Commonly, autologous SEDs are used, but they are replaced more and more by allogeneic SEDs prepared from donor serum. Allogeneic SED are derived from healthy voluntary, non-remunerated male donors with blood group AB. The use of allogeneic SED could provide blood bank controlled quality, a safer product in larger quantities that is quickly available for each patient. No double-blind randomized trials are known to exist to detect a difference in result between the effect of allogeneic SED or autologous SED. This pilot study is intended to obtain insight in the ability of autologous and allogeneic SEDs to improve patient dry eye sensation. Our hypothesis is that autologous SEDs (in a 1:1 dilution with saline) result in an improvement of the patient dry eye sensation, while allogeneic SEDs (in a 1:1 dilution with saline) do not.

Study Arms (2)
Group A
EXPERIMENTALSubjects assigned to this arm will receive autologous serum eye drops first, followed by a washout period and then allogeneic serum eye drops.
Group B
EXPERIMENTALSubjects assigned to this arm will receive allogeneic serum eye drops first, followed by a washout period and then autologous serum eye drops.
Interventions
Autologous serum eye drop doses will be 6 times daily in each eye
Allogeneic serum eye drop doses will be 6 times daily in each eye
