Abstract
Purpose :
Realize a comparative analysis of the retinal thickness after performing the Nd:Yag Laser for capsulotomy stratification by energy. Associating the variance or maintenance of that with total energy or even with the energy used in every shot.
Methods :
A clinical trial was performed correlating the macular thickness before and after the Nd:Yag Laser in 14 eyes of patients diagnosed with posterior capsule opacity at the Instituto de Olhos de Goiania.
Patients with vision less than 0.3 were included and there were no other ocular or systemic alterations that justified low visual acuit. Macular thickness was obtained through Optical Coherence Tomography and Nd:Yag Laser was performed following random energy patterns justified by the degree of opacity.
The patients were randomly selected and submitted to the capsulotomy procedure with Nd:Yag Laser. The macular thickness was measured before and after 5 days of the procedure with subsequent correlation between the total energy used stratified by pulses.
From a total of 14 eyes among which 5 were male patients and 9 female patients, ranging in age from 50 to 79 years, it can observed that macular thickness remained constant in the majority of patients, and a small increase were observed in patients where a greater amount of total energy independent of the energy per pulse was used.
Results :
From a total of 14 eyes among which 5 were male patients and 9 female patients, ranging in age from 50 to 79 years, it can observed that macular thickness remained constant in the majority of patients, and a small increase were observed in patients where a greater amount of total energy independent of the energy per pulse was used.
Conclusions :
The macular thickness didn’t undergo significant variation stratified by the energy in this trial. Therefore, there are many studies that perform the increase of retinal thickness after yag laser for capsulotomy, showing us the necessity of analise the risc factors constantly related.
