During the study, patients will receive one of the treatments before their eye surgery. The study will measure pain and anxiety levels at different times: when patients first arrive, before the numbing injection is given, right after the injection is given, and immediately after the surgery is completed. Pain will be measured using a scale where patients rate their pain level, and anxiety will be measured using questionnaires that ask about feelings of nervousness or worry. The study will also record how long it takes to give the numbing injection behind the eye.

Patients participating in this study will be adults over 18 years old who need surgery on one eye only. The treatments being tested are taken by mouth in tablet form. The study aims to understand whether these approaches can make the surgical experience less painful and less stressful for patients undergoing this type of eye surgery with retrobulbar anaesthesia.

During the study, participants will use different types of eye drops. The research will monitor several aspects of eye health, such as conjunctival hyperaemia, which is an increase in blood flow that makes the white part of the eye look red, and ocular pain or discomfort. The study also looks at central macular thickness, which refers to the thickness of the part of the retina responsible for sharp, central vision, using a specialized imaging method called optical coherence tomography. Other factors monitored include intraocular pressure, which is the fluid pressure inside the eye, and best corrected visual acuity, which is the clearest vision possible with the help of glasses or contact lenses.

The medications being studied include NEVANAC (nepafenac) and Spersadex (dexamethasone), both of which are administered as eye drops. NEVANAC is a non-steroidal anti-inflammatory drug (NSAID) that helps reduce inflammation and pain, while Spersadex is a corticosteroid that also helps in reducing inflammation. The study will compare the effects of these medications on postoperative inflammation to determine the best approach for managing inflammation after cataract surgery.

Participants in the study will receive one of the medication regimens before their cataract surgery. The study will monitor the level of inflammation in the eye after the surgery to assess the effectiveness of the medications. The goal is to find the most effective way to manage inflammation, which can help improve recovery and outcomes for patients undergoing cataract surgery.

The purpose of this research is to determine if preservative-free eye drops work better than preserved eye drops after cataract surgery. During the study, participants receive either preservative-free or preserved eye drops for their post-surgery treatment. The treatment continues for 4 weeks after the cataract surgery.

Both types of eye drops contain the same active medicines – dexamethasone, which reduces inflammation, and diclofenac, which helps manage pain and inflammation. The only difference between the two treatment groups is that one contains preservatives while the other does not. The study measures various aspects of eye health, including tear production, eye surface condition, and inflammation levels.

The purpose of this study is to evaluate how effective and safe Mydrane is when used in children. During the study, children who are scheduled for cataract surgery will receive an injection of Mydrane. The study will monitor how well the pupil dilates, which is important for the surgery to be performed without needing additional mechanical dilation. Additionally, the study will observe any changes in heart rate and blood pressure to ensure the safety of the medication.

Participants in the study will be children aged 8 weeks to 17 years who are undergoing cataract surgery. The study aims to provide valuable information on the use of Mydrane in pediatric patients, helping to improve surgical outcomes and ensure the safety of young patients undergoing this procedure.
