Anonymous • Basalioma

Ghana

Verified review.

The surgeon was excellent

What surprised me most about my basalioma treatment wasn't the procedure itself, but the detailed skin examination I received. The surgeon was excellent. He made sure all removal options were discussed clearly, which was reassuring since I already had my diagnosis before arriving. Right now, the treated area is healing very well. While the medical care was superb and the clinic facilities are great, the administrative staff seemed a bit disorganized, which was the only downside. Despite that, based on the surgeon’s work, it’s a place I would suggest to others.

My Bookimed coordinator was highly skilled, had the passion and patience for her work and that translated to the numerous array of options provided to me to choose from based on my budget during the entire process.She interacted with me 24/7 just for us to have solution within my schedule. All information (proforma, visa assistance, travel guidance and estimated personal expenses) for the entire treatment were on point and I encourage all manner of persons seeking medical treatment abroad to choose Bookimed as their medical tourism partner.

1. Interpreter only come when the patient calls for his services and that is only during the day. If the interpreter can also support beyond the interactions with the specialist. 2. Airport and Internal movement are left to the patient to handle which can sometimes be a major challenge for some category of patients and given the language barrier. 3. Hospital discharges are very strict even if you the patient feels he/she need additional day(s) to be fit for a return to the hotel to continue the recovery.

IURIE • Keratoplasty

Moldova

Jun 20, 2026

I can wholeheartedly recommend the Memorial Şişli Clinic. I underwent a deep anterior lamellar keratoplasty (DALK) on my left eye, and I now feel better than I had expected. I would like to express my sincere gratitude to the coordinating doctor, Sergey, and Dr Abdallah ÖZCAYA for their expertise and responsible approach. I particularly remember how Dr ÖZCAYA personally checked on me after the operation — this gave me confidence and peace of mind. The clinic was always available, and there were no additional costs. A special thank you to the interpreter, Daniela, for her excellent translation and constant help with communication.

The surgeon dr ozturk was fantastic, friendly, knowledgeable and inspired confidence immediately

My biggest worry was what recovery would feel like this time, especially after having my old implants for well over ten years. It turned out to be about the same as my first surgery. The surgeon dr ozturk was fantastic, friendly, knowledgable and inspired confidence immediately performing a position adjustment and implant replacement, though it's still hard to compare the final result as surgery was only 5 days ago. The hospital facility was clean and private room was great. My main issue was with the general staff support, which could have been more attentive, having said that whenever I called they attended immediately and were kind. Despite that, the medical care itself was solid, and I'm satisfied with the outcome.

Translator amazing as was Dr Ozturk, friendly, professional, knowledgeable. Co-ordination of transport, Appointments etc smooth

Hospital staff could’ve been more proactive eg not leaving things out of reach, ensuring drinks etc on hand, although having said that they immediately attended any call bells and were kind, I just didn’t want to trouble them more than I needed to.

Anonymous • Immunotherapy with Keytruda (Pembolizumab)

The doctor and all the staff have been very attentive and professional, which gives me confidence that I made the right choice of clinic and treatment process

My main concern before starting treatment was how my body would react to the drug. I’m undergoing a course of Keytruda immunotherapy for kidney cancer, receiving an infusion every three weeks. Yes, I have experienced some side effects. These are mainly digestive issues, and I feel a little more tired. Of course, I am still concerned that these might get worse over time. But I must say that the doctor and all the staff have been very attentive and professional, which gives me confidence that I made the right choice of clinic and treatment process.

I’m very grateful

My biggest worry was that my nose would look unnatural and that the result wouldn’t live up to my expectations. Now, even though I’m still recovering, I can see that I was worrying for nothing. They removed a small bump, and the bridge of my nose is straighter, just as I’d hoped. I’d also like to mention that the tip of my nose now looks more refined. My breathing has improved too. I think ultrasonic piezorhinoplasty was the right choice. The whole team, from the staff to the surgeon, were very attentive and professional, which helped me feel at ease. I’m very grateful.

We loved everything; the organisation was top-notch. A special thank you to our coordinator, Valentina. They helped us sort everything out and were always on hand. Thank you so much 🙏🏻❗️
