SUMMARY

Aim – comparative estimation of the role of temporal and upper incisions in the cataract phacoemulsifcation of postoperative astigmatism development.

Material and methods
Since April to October, 2016 the phacoemulsifcation surgery was performed on 113 eyes (87 patients) in the department of surgery and corneal transplantation of the National Centre of Ophthalmology named after acad. Zarifa Aliyeva. The age of patients was wilhin 36-98 years. For the comparative analysis on the left eye of 54,87% (62 eyes) there was made the temporal and on the right one 45,13% (51 eye) – the upper corneal incisions.

Results
At the 3th month postoperatively the degree of astigmatism lower than 58,43% (30 eyes), higher than 0,75- 41,57% (21 eyes) of cases on the right eyes. On the left eyes the degree of astigmatism lower than 0,75 was 73,66%, higher than 0,75 – 26,34% of cases. But the attention was attracted to the increase of degree of astigmatism on 0,5 in 2 eyes where the left temporal incision was used. On eyes with left temporal incision the visual acuity on average was 0,8, on right eyes with upper incision – 0,7.

Conclusion
Surgical intervention depends on the bony skeleton of orbit. Besides, during the surgery the temporal incision creates conditions for irrigation solution. Temporal corneal incisions refractively are more stable due to the remote distance from the visual axis. During the upper corneal incisions because of the pressure in the zone of incision on the upper eyelid is the cause of fuctation and so as compared with the temporal incisions, increases the possibility of incorrect astigmatism development.
