- Planning Your Visit

Same Day Surgery and LASIK Patients

Contact lenses

If you wear contact lenses and are coming in for an evaluation or surgery, it is very important that you stop wearing soft lenses at least 14 days prior to your visit and gas-permeable lenses at least 21 days prior to your visit.

Eye infection

If you have any symptoms of an eye infection, please let us know so that it can be treated prior to your visit.

Responsible adult

If you are having surgery, you need to bring an adult who drives and can remain with you throughout the day. Patients are NOT allowed to drive after surgery. Since seating is limited, we ask that only one person accompany you. If your postoperative care will be done at Carolina Eye, you will also need for someone to drive you back to the center the next day.

RK, LASIK, or other past refractive surgery

If you had previous refractive surgery like RK or LASIK done at another center, please bring copies of the eye measurements that were taken before your surgery.

Day before surgery

Please do not drink any alcoholic beverage within 24 hours of your surgery. Take a laxative if you are constipated.

Day of surgery

Shower and wash your hair. Remove fingernail polish and do not wear makeup. Wear clean and comfortable clothes since you will be changing out of them into a surgical gown. Secure long hair with a rubber band. Do not wear metal clips or bobby pins. Unless you are instructed otherwise, eat a light breakfast. Take your morning medications as scheduled. Last, gather together the items noted in What to Bring With You.

Planning Your Visit

You will be in caring hands during your entire visit, and we will do all we can to make you feel at ease. If at any time there is anything we can do to help, please do not hesitate to let us know. Please note that if you are having your evaluation and surgery both in the same day (same-day surgery patient), you will be at the center almost the entire day for tests, evaluations, and surgery. If this is the case, you will want to dress comfortably and bring a snack as well as something to occupy your time.

If this is your first appointment with us, we encourage you to go to the Forms page and download the new patient forms. Bring the completed forms with you. You might want to also print out the New Patient Information Guidelines. These Guidelines include information on appointments, billing and insurance, financing options, out-of-town visitors information, and planning for your visit.

What to Bring with You

Bring your New Patient forms if you are a new patient.
Bring your insurance cards or other policy information and identification. If your insurance provider requires preapproval, bring the approval form.
Bring a complete list of the nonprescription and prescription medications and dosages you currently are taking, including eye drops and ointments. (It may be easiest to just bring all your medication bottles.)
Bring the names and phone numbers of your family eye doctor and family medical doctor.Bring a consultation letter, note, or Request for Consultation form if you are being referred by your family eye doctor. It is important that you bring (do not mail) this information.
Bring a snack or lunch, especially if you are diabetic. Limited items are available from our vending machines.
Bring a book to read or something else to occupy your time.
Bring your overnight bag if you are staying at a local hotel.
Last, bring a sweater or jacket since we keep the temperature in the clinic rather cool.
