Randomized Controlled Trial Comparative Study Clinical TrialNo-anesthesia clear corneal phacoemulsification versus topical and topical plus intracameral anesthesia. Randomized clinical trial.
To compare the intraoperative pain scores during clear corneal phacoemulsification under no anesthesia, topical anesthesia, and topical plus intracameral anesthesia. ⋯ No-anesthesia clear corneal phacoemulsification was performed by a highly experienced, skilled surgeon without causing an unacceptable level of pain. However, this technique is not suitable for every cataract surgeon or patient.

Randomized Controlled Trial Comparative Study Clinical TrialTopical anesthesia with or without propofol sedation versus retrobulbar/peribulbar anesthesia for cataract extraction: prospective randomized trial.
To evaluate the feasibility of intravenous sedation in addition to topical anesthesia during cataract extraction. ⋯ Intravenous propofol sedation added to topical anesthesia did not improve the operative conditions or surgical outcome. Retrobulbar/peribulbar anesthesia ensured the best surgical conditions. Patients in all anesthesia groups reported high satisfaction. However, patients having bilateral surgery seemed to prefer combined anesthesia over retrobulbar/peribulbar anesthesia.

Randomized Controlled Trial Comparative Study Clinical TrialTopical plus intracameral lidocaine versus retrobulbar anesthesia in phacotrabeculectomy: prospective randomized study.
To compare the efficacy and safety of topical and retrobulbar anesthesia for phacotrabeculectomy. ⋯ Topical anesthesia supplemented with intracameral lidocaine was an effective alternative to retrobulbar anesthesia for phacotrabeculectomy. Although the degree of patient discomfort was significantly higher during surgery under topical anesthesia, the method avoids the pain and complications associated with a retrobulbar injection.

Randomized Controlled Trial Comparative Study Clinical TrialTopical versus sub-Tenon's anesthesia without sedation in cataract surgery.
To compare pain control using topical anesthesia with that using sub-Tenon's anesthesia for clear corneal phacoemulsification cataract surgery and foldable intraocular lens (IOL) implantation. ⋯ Patients having cataract surgery under topical anesthesia had more intraoperative and postoperative discomfort than patients receiving sub-Tenon's anesthesia. However, patients having topical anesthesia reported less pain during its administration and had fewer complications. Both anesthesia methods provided high levels of pain control without additional sedation.

Randomized Controlled Trial Comparative Study Clinical TrialEffect of intracameral acetylcholine on latanoprost in preventing ocular hypertension after phacoemulsification and intraocular lens implantation.
To evaluate the effect of intracameral acetylcholine on latanoprost in preventing ocular hypertension in the early period after phacoemulsification with posterior chamber intraocular lens (PC IOL) implantation. ⋯ A single application of latanoprost did not significantly lower IOP in the first 24 hours after phacoemulsification with PC IOL implantation. Eyes receiving intracameral acetylcholine alone had a significantly greater decrease in IOP than control eyes at 3 hours but not at 24 hours. The addition of intracameral acetylcholine to latanoprost did not enhance or reduce latanoprost's IOP-lowering effect.
