Purpose
To compare the use of partial thickness and full thickness limbal relaxing incisions (LRI) during phacoemulsification for treatment of with-the-rule astigmatism in senile cataract patients.
Setting
Vanak Eye Surgery Center, Tehran, Iran.
Methods
In this prospective randomized controlled trial, 88 older than 65 years patients with by the rule astigmatism cylinder of over 1.25 were included. The patients were randomly divided and either received two partial thickness or one partial thickness and one full thickness corneal incision in limbus area to correct their astigmatism.
Results
One month postoperatively the mean BCVA (P=0.12) and UCVA (P=0.011) correction was higher in the partial thickness group but this difference was not significant at six months. There was no significant difference between the two groups regarding spectacle independence, photophobia, foreign body sensation and patient satisfaction.
Conclusions
Since a full thickness LRI might lead to complications (leakage, endophthalmitis) in rare cases and does not result in better astigmatism correction it is suggested that partial thickness LRI should be considered as the preferred method.
