Purpose:
To evaluate anterior segment parameters in patients undergoing sutureless scleral fixation intraocular lens implantation with the modified Yamane technique (SSF-IOL-MY) by using Scheimpflug camera system.
Methods:
Each group of 25 patients was included for aphakia undergoing SSF-IOL-MY and for senile cataract undergoing uneventful phacoemulsification and intraocular lens implantation (Phaco+IOL). Anterior chamber depth (ACD), iridocorneal angle (ICA), anterior chamber volume (ACV) and keratometric values were evaluated by Scheimpflug camera (Sirius, CSO, Italy) system.
Results:
It was seen that the ACD, ICA and ACV display wider structures in patients with SSF-IOL-MY group compared to Phaco+IOL group. However, the ACD (p = 0.828) and ICA (p = 0.219) have not a statistically significant difference, while ACV (p = 0.007) has a statistically significant difference. In terms of keratometric values of the patients, there was no statistically difference in K1, K2 and Kmax values (p = 0.348, p = 0.106, p =0.269, respectively). Although there was no statistically significant difference between the groups in terms of anterior corneal astigmatism, posterior corneal astigmatism was statistically higher in the Phaco+IOL group (p = 0.192, p = 0.031, respectively).
Conclusion:
SSF-IOL-MY surgery affects anterior segment parameters similar to the Phaco+IOL method, which is the gold standard in cataract surgery. In this surgery, it was approached to the gold standard method in terms of IOL position with the ACD, ACV and ICA values and the results of the corneal incision with the keratometric values.
