Purpose:
Laser Blended Vision for Presbyopia by Zeiss is a wavefront-guided treatment that has several mechanisms to increase near vision keeping a good vision for distance as well: monovision,depth of field,spherical aberration,vertex centration,retinal image processing,neural summation,blur adaptation and neural suppression.We wanted to study the results of the first 70 patients that underwent this treatment for presbyopia in our Clinic.
Setting:
Retrospective study of the first 70 patients that underwent LASIK with the wavefront-guided Laser Blended Vision Programme for Presbyopia by Zeiss during 2011 in our Clinic (Optima Laser Eye Clinic Valencia).
Methods:
We studied the first 70 patients with presbyopia that underwent LASIK with the wavefront-guided Laser Blended Vision Programme by Zeiss in our Excimer Laser Zeiss Mel-80 during 2011. The programme has a non-linear aspheric ablation profile that increases the spherical aberration in both eyes. It also produces a slight myopia between -1.0 and -1.5 spheres in the non-dominant eye. We analysed the results and patient’s satisfaction. The patients were separated into two groups: less than 50 years old and 50 years or more. The follow-up was between 1 to 7 months. RESULTS 36 male and 34 female patients between 42 and 69 years old.Only 3 patients (4.29%) were between 42 and 44;25 (35.71%) were between 45 and 49; 42 patients (60%) were 50 years or more.4 patients underwent the surgery in the non-dominant eye only.12 (17.14%) patients were emmetropic (0.5 o less spherical equivalent), 18 (25.71%) were myopic or astigmatic myopic and 40 (57.14%) were hyperopic or astigmatic hyperopic.54 patients (77.14%) had a pre-op Jäger near vision between J4 and J10. 68 patients (97.14%) had a post-op near vision between J1 and J3; 62 (88.57%) had J1.Post-op visual acuity without correction for distance was 20/20 or more in 66 patients (94.29%) (both eyes open).82.14% of patients of 49 years or less had a visual acuity for distance of 16/20 or more in the non-dominant eye with an average spherical equivalent of -1.0 .Only 23.8% of patients of 50 years or more had that visual acuity in the non-dominant eye with an average spherical equivalent of -1.5. 88.57% was satisfied with the procedure,the rest did not have any important complication:5.71% needed an enhancement and 5.71% did not achieve their expectations.6 patients (8.57%) needed an enhancement, 5 of them(83,3%) only of one eye.
Conclusions:
Laser Blended Vision for presbyopia has a high percentage of satisfaction for emmetropic, myopic, hyperopic and astigmatic patients with a fast adaptation and very good outcomes in visual acuity for distance and near.The results are as good for younger patients with presbyopia as for older patients.Though they adapt, patients over 50 perceive more the difference of vision of both eyes.Satisfaction is not always related to visual acuity,image processing is important to give a comfortable vision.Achieving all patients’ expectations is not always possible.The higher percentage of enhancements and higher patient’s expectations compared to standard LASIK could influence in patient’s satisfaction.
