Your hyperopia is indeed high. Hyperopic Lasik
is more challenging than Lasik for those who are myopic (nearsighted). High hyperopia is even more challenging, however you are within a treatable range and you do have several options.
Something that is unique about farsighted Lasik is that the older you are the greater the potential benefit. For most patients Lasik is to reduce the need for glasses. This is a matter of convenience or cosmetics. A sub-group of patients who have hyperopic Lasik are actually likely to see better after Lasik than they could see before Lasik with glasses. This is because of something called presbyopia.
The natural crystalline lens within the eye changes shape to focus on near objects. This is called accommodation. Many people who have low to moderate farsighted vision are able to accommodate enough that glasses are not required. Some hyperopes can "focus around" the hyperopia.
As we age the ability of the crystalline lens to accommodate is diminished. This natural process is called presbyopia and for most people does not become a problem until around age 40. Presbyopia is when you need reading glasses to see things close. People who are hyperopic and presbyopic often cannot see well at any distance even with glasses or contact lenses. For these people Lasik may provide better quality vision than glasses or contact lenses. In other words, a hyperope/presbyopia has more to gain from Lasik than a hyperope or myope (nearsighted) person without presbyopia.
It is likely that you will need enhancement surgery to resolve regression of effect common with hyperopic Lasik. You should consider the surface ablation techniques of PRK, LASEK, or Epi-Lasik as an alternative to Lasik. Surface ablation techniques may be more conducive to repeat surgeries.
