In Vitro Fertilization with Unknown Sperm Donor

Long story short, my wife and I have both agreed we want to start a family. The only hesitation is on my end because of my genetics. I suffer from high blood pressure and severe allergies/asthma, both of which are strongly hereditary and run in my family. And while it hasn't impacted me yet, major vision problems also run in my family. Both my dad and my older sister are legally blind without glasses or contacts.

I want a child but I don't want to pass along my faulty genetics. We are seriously considering doing IVF with sperm from an unknown donor, not my own sperm. My wife's only concern is that I won't have the same level of connection with the child knowing genetically it's not my own. I personally don't have that concern.

Has anyone else here done this? What was your experience? Did it cause any impact with your relationship with the child (any thoughts of feeling like the child really isn't yours)? Any impacts down the road when the child was older?
