Pupil size after mydriatics [ Time Frame: no longer then 1 year ] [ Designated as safety issue: No ]
We would like to evaluate whether Pupil size dilated with Intracameral Lidocaine 1% is as effective dilator compared with Topical Cyclopentolate 1% and Phenylephrine 10%

Lidocaine Usage for Pupil Dilatation (Mydriasis)
Efficiency and Safety of Lidocaine Usage for Pupil Dilatation (Mydriasis) During Cataract Surgery

The purpose of this study is to determine if the mydriatic effect of intracameral lidocaine 1% is as effective as topical cyclopentolate 1% and phenylephrine 10% for achieving effective mydriasis during phacoemulsification surgery.

Former studied done on the effect of Intracameral lidocaine 1% compared to topical mydriatic agents for achieving effective mydriasis during phacoemulsification surgery have compared 2 different groups of patients, ie; One group received topical agents and the other received intracameral lidocaine. The resultant pupil size was recorded and evaluated in the 2 groups. Our purpose is to compare the effect of these agents on the same group of people.

Patients recruited will be invited first for evaluation at least 1 week before the surgery. During this evaluation 1 dose (drop) of topical cyclopentolate 1% and Phenylephrine 10% will be instilled to the evaluated eye 3 times at 10 minutes intervals. After 1 hour from the last instillation pupil diameter will be recorded. In the second part of this study during the phacoemulsification surgery patients will be given intracamerally lidocaine 1% (0.2 ml) and the pupil size will be recorded after 90 seconds. the resultant values will be evaluated/compared.

Endpoint Classification: Safety/Efficacy Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Supportive Care
Cataract
Drug: Lidocaine 1% (sterile)
during the phacoemulsification surgery patients will be given intracamerally lidocaine 1% (0.2 ml) and the pupil size will be recorded after 90 seconds
Other Name: Lidocaine 1% (sterile)
Experimental: Lidmyd
The same group is used for the first and the second part of the experiment. Initially the patients will be given topical cyclopentolate 1% and Phenylephrine 10% and the pupil diameter will be recorded. In the second part of the experiment lidocaine 1% will be introduced intracamerally and the pupil size will be recorded again. The 2 measurements will be statistically compared/evaluated.
Intervention: Drug: Lidocaine 1% (sterile)
