Purpose: To investigate the surgical and functional clinical outcomes of the IntraCOR , intrastromal application for presbyopia correction with FEMTEC (Technolas Perfect Vision AG) femtosecond laser in Istanbul Surgery Hospital.

Method: In a prospective clinical study IntraCOR presbyopic laser correction performed on 155 eyes of 100 mild hyperopic or emmetropic patients latest results are evaluated. Preoperatively routine eye examination included distance vision (Snellen) and near vision (Jaegger), intraocular eye pressure, corneal thickness, fundoscopic evaluation,and contrast sensivity test . The patients underwent intrastromal photodistruption with Femtec femtosecond laser. The photodistruption pattern customised to each patient regarding keratometric values, refraction, age and corneal thickness. The patients followed postoperativley 1st day, 1st week and 1st month, 6th month and 12th month.

Results:: The mean age of the patients is 52.2 (43–68). Follow up time is 1 month–12 months since February 2008. One year results revealed a stable Uncorrected Near Visual Acuity(UNVA) with statistically significant gain from mean J13 to J3 (J7-J1) (p<0.001). Preoperative Uncorrected mean Distance Visual Acuty improved from 0.72 (0.10–1.00) to 0.82 (0.40–1.00) postoperatively.

10 eyes (6.45%) lost 1 snellen line and 5 eyes (3.2%) lost 2 Snellen lines on Best Corrected VA because of late onset of corneal haze or decentered treatment zone (2 eyes). Enhancement teratment as PRK performed on 10 eyes (6.45%) because of regression on previous hyperopia or overcorrection. 2 patients developed cataract after IntraCOR and had Catarct operation with Monofocal IntraOcular Lens and improvement observed both on Distance and near Visual accuity.

Conclusion: One year is over on our experience with IntraCOR treatment. After the learning curve ,we changed our patient selection and postoperative medical protocol and the recent results appear with beter results. This new femtosecond laser based treatment shows stable refractive outcomes and 90% patient satisfaction in presbyopia correction.
