Why Maximum Plus & Minimum Minus in Refraction?

OPTOMETRY WITH KHURRAM
Why we should prescribe Maximum Plus and minimum Minus in subjective and objective refraction.

[@veena1300]

I randomly scrolling down KZbin video and i saw yours one. After watching your video i felt your concept is very clear and easy to understand so i personally want you to make more and more videos of this field and requesting you to make some videos of optical part also. Beacuse for optometrist clinical and optical both part is equally important ❤️❤️❤️😍😍😍😍

[@optometrywithkhurram6867]

Thank you for your compliment..sure I will upload your concerns. 🌸

[@otiebrown9999]

Excellent! I check my own refractive state with this concept . Thank you

[@rinasc7225]

Hi Khurram. What about in high myopes? When overcorrection yields much better visual acuity and increases quality of everyday life activities? Multifocals?

[@otiebrown9999]

Looking for the point of "just blur", on the 20/20 line.

Can you please say me how do minus lens stimulate accommodation? Because as i have studied during use of minus lens our eye lens flattens and accomodation is relaxed.

Why we not give exact correction of myopia

[@optometrywithkhurram6867]

Overcorrection of myopia always induse accommodation.. So thats why we avoid Overcorrection of myopia or for the safe side full correction of myopia...

Sir when we start subjective refraction we first take best visual acuity with sphere,than if astigmatism is present we refine axis and power of cylinder.but in books it is written that final step of monocular refraction is refining sphere.plz explain this

[@optometrywithkhurram6867]

The last step of refraction is binocular balancing dear

[@otiebrown9999]

In objective science, the accommodation system is "never at rest".

[@bheshrajchaudhary9737]

You explained overcorrection for myopia but what will happen if myopia is under corrected and rays are still focused infront of retina not on retina? Pt still may complain of blurry vision.

[@masterwatch4856]

Hmm

[@otiebrown9999]

I also agree! Maximum plus for reading, when I am at 20/50. No minus for distance. Result? Slowly my refraction changes from 20/50, to 20/20. Or from -0.75 Diopters, to +0.25 Diopters, and my eyes are no longer nearsighted. Thank you Doctor, for my success! If only more young science students would understand the concept.

[@optometrywithkhurram6867]

Myopic power always declined with age..

And sounds good.tbat you are not nearsighted anymore.🌸

[@takursh9897]

Hii sirr. My question is . If patient is not fogged prior to beginning subjective refraction . ? Please give me a answer this question. please sir..

[@optometrywithkhurram6867]

Actually fogging makes accommodation relax...which is necessary for better result and prescription. But if you have better skills and experience then you can go without fogging. But I must say that fogging is better to perform.

[@yarramalarishitha4121]

Thank u sirr , very informative

[@optometrywithkhurram6867]

Most welcome

[@mayaarish6267]

Sir very nice Respected sir As by under-correcting the hyperopia (by exertion of accommodation (AC/A:) pts eye can have convergent squint So similarly in case of over-correction of myopia as pts can have asthenopic symptoms due to exertion of accommodation (same as in above case) So sir can this patient of myopia have divergent squint ? Anything like this👆??

[@optometrywithkhurram6867]

Yes you are right. Hyperopes are always prone to convergent and myopes always prone to divergent squint.

[@optometrywithkhurram6867]

Great. But I am worried that who's face you were searching in Moon by the way ?😐😁

[@menukasuwal9723]

made me confused....... what will happen if we undercorrect myopic eye??? if we correct myopic eye with low minus the rays wonnt focus on retina and the image will still be blurr....

[@optometrywithkhurram6867]

As I mentioned in video..under correct doesn't mean we undercorrect it more than 0.50..but just least..like 0.25 or less. Because the property of minus concave lens is, its always make object more sharper and clearer when we increase from best corrected prescription,so if we increase 0.25 from best correction then patient will obviously prefer..that's why chances of mistake are always there..that's why we always undercorrect in myopic prescription..

[@optometrywithkhurram6867]

Thankyou..sure..

[@mafia1270]

Thank you..correct me if im wrong..so this could mean that if you over refract with minus, there is a tendency that the eye will become hyperopic instead of neutralizing it

[@mafia1270]

But i am practising that maximum plus and minimum minus..but sometimes i also get confused if i will undercorrect or give the full correction to my patients especially to children 4- 12 yrs old..i hope you could also make a lecture regarding refraction on children especially with amblyopia and strabismus..thank you for all the lectures and responding to all my questions

[@optometrywithkhurram6867]

Yes ..now you get the point.. We always undercorrect a myope under the fear of being hyperope.. And if a myope becomes hyperope by overcorrect it, then again he or she will use accommodation,which is not good.
