Abstract
Cataract is responsible for half of the global burden from vision impairment. In the western world, phacoemulsification is the surgical procedure of choice routinely providing excellent visual and safety outcome.
Femtosecond laser is now commercially available to perform three key steps in small incision cataract surgery: capsulotomy, lens fragmentation and wound construction. Treatment of astigmatism is also possible for certain cases.
Current research suggests that the use of femtosecond lasers in cataract surgery will provide selective benefits both for the surgeon and the patient; however, there remains little if any evidence that femtosecond cataract surgery provides superior safety or visual outcomes as compared with conventional phacoemulsification.
This study aimed to evaluate the efficacy, complications, advantages and disadvantages of use of femtosecond laser in cataract surgery.
Design of this study was a randomized prospective interventional clinical study that was conducted in I-Care Hospital, Alexandria, Egypt in the period from May 2015 to October 2016.
This study included fifty eyes of fifty patients that were diagnosed as having Grade III nuclear senile cataract, and subjected to femtosecond laser assisted cataract surgery (FLACS) with the follow up duration of one year.
All patients had been followed up for change in UCVA, BCVA, refraction, Keratometry, intraocular pressure and specular microscopy. The results of this study showed improvement in all parameters with no adverse effects in intraocular pressure and in endothelial count.
Very few complications related to femtocataract technique were reported in our study including incomplete capsulotomy, incomplete corneal incisions, incomplete lens fragmentation and postdocking significant conjunctival ecchymosis.
Other complications related to phacoemulsification and IOL implantation such as capsular block syndrome, difficult cortical removal, extension of capsulotomy, posterior capsular tear and vitreous loss were not reported in our study.
